THE IMPACT IT'S HAD ON HER AND WHY SHE'S PUSHING THOSE ADULTS UP ON CAPITOL HILL TO HELP PROTECT OTHER CHILDREN FROM FALLING VICTIM TO MASS SHOOTERS. >> ALL RIGHT. AND WE BEGIN WITH THE DRAMATIC RELEASE OF BRITTNEY GRINER, THE WNBA STAR HEADING BACK TO THE U.S. AFTER NEARLY THREE HUNDRED DAYS OF IMPRISONMENT BY ADMINISTRATION ,STRIKING A DEAL WITH THE KREMLIN TO RELEASE A CONVICTED RUSSIAN ARMS DEALER, VIKTOR BOUT, IN EXCHANGE FOR GRINER. PRESIDENT BIDEN TWEETING THIS PHOTO OF HIM ON THE PHONE WITH HER, CONFIRMING THAT SHE WOULD BE COMING BACK HOME MONTHS AFTER INTENSE NEGOTIATIONS. THE PRESIDENT ALSO SPEAKING AT THE WHITE HOUSE TODAY ALONGSIDE GREINER'S WIFE, SHERYL. >> TAKE A LISTEN. THIS IS THE DAY WE WERE TOLD FOR A LONG TIME WE NEVER STOPPED PUSHING FOR HER RELEASE. IT TOOK PAINSTAKING, INTENSE NEGOTIATIONS. AND I WANT TO THANK ALL THE HARDWORKING PUBLIC SERVANTS ACROSS MY ADMINISTRATION WHO WORKED TIRELESSLY TO SECURE OUR RELEASE. FOR MORE, LET'S BRING IN ABC NEWS INVESTIGATIVE REPORTER AARON KATERSKY. ALSO ABC NEWS JAY O'BRIEN, WHO IS LIVE ON CAPITOL HILL, AND OUR PHIL LIPOF, WHO'S BEEN FOLLOWING EVERY DETAIL, THIS STORY OUT OF NEW YORK. SO AARON GRINER NOW ON HER WAY HOME. LET'S TALK ABOUT WHAT WE KNOW ABOUT HER CONDITION. WE ARE GETTING INFORMATION NOW. SHE IS IN ROUTE TO BROOKE ARMY MEDICAL CENTER IN SAN ANTONIO. THAT HAS BEEN CONFIRMED THROUGH A SPOKESPERSON THERE. SHE'LL ACTUALLY LAND AT THE AIR FORCE, KELLY FIELD, RIGHT NEARBY. AND THAT'S STANDARD FOR WHEN PEOPLE COME HOME FROM OVERSEAS UNDER THESE KINDS OF CIRCUMSTANCES, KYRA, THEY THEY WANT TO GET CHECKED OUT MEDICALLY. BUT BY ALL ACCOUNTS, ACCORDING TO THE PRESIDENT AND THE WHITE HOUSE, SHE'S DOING FINE AND IS IN GOOD HEALTH AND MAYBE MORE IMPORTANTLY, IN GOOD SPIRITS. VERY UPBEAT MOOD, ACCORDING TO A SENIOR ADMINISTRATION OFFICIAL. RELIEVED CERTAINLY TO BE COMING HOME AND WILL SHARE IN THE MOMENT WITH HER WITH HER WIFE AND HER FAMILY AND HER WIFE TOLD US THAT THAT BRITTNEY GRINER NEVER REALLY LOST HOPE, NEVER LOST HER SPIRIT, AND THAT'S WHY SHE WAS ABLE TO ENDURE THESE THREE HUNDRED PLUS DAYS IN RUSSIAN CAPTIVITY. YES, SIR. SURE MAKE YOU RESILIENT. AND BOY, DID SHE HAVE A LOT OF LOVE BACK HERE IN THE STATES AS WELL FROM SO MANY PEOPLE. AND FILL THIS MOVE COMES AS FORMER MARINE PAUL WHEELIN IS STILL IN PRISON THERE IN RUSSIA. AND WE ARE HEARING FROM HIM AS WELL. HE'S HAPPY CLEARLY BRITTNEY GRINER, BUT HE'S VERY DISAPPOINTED THAT HE IS STILL THERE. IN PRISON COMING ON FOR YEARS NOW KYRA. >> YOU'RE RIGHT, PAUL. WHEELING HIMSELF MADE A CALL TO CNN FROM A PRISON CELL IN RUSSIA. AND YOU'RE RIGHT, THE FIRST THING HE SAID IS THAT HE WAS VERY GRATEFUL THAT BRITTNEY GRINER BEEN RELEASED. BUT THEN HE SAID THIS. I'M GREATLY DISAPPOINTED THAT MOORE HAS NOT BEEN DONE TO SECURE MY RELEASE, ESPECIALLY AS THE FOUR YEAR ANNIVERSARY OF MY ARREST IS COMING UP. I WAS ARRESTED FOR A CRIME. IT NEVER OCCURRED. I DON'T UNDERSTAND WHY I AM STILL SITTING HERE. >> YOU KNOW, HE MADE THAT STATEMENT AND THEN HE WENT ON TO DIRECTLY MAKE A PLEA TO PRESIDENT BIDEN AND LISTEN, I WOULD SAY THAT IF THE MESSAGE COULD GO TO PRESIDENT BIDEN THAT THIS IS A PRECARIOUS SITUATION, THAT YOU YOURSELF QUICKLY AND I WOULD HOPE THAT HE AND HIS ADMINISTRATION WOULD DO EVERYTHING THEY COULD TO GET ME HOME REGARDLESS OF THE PRICE THEY MIGHT HAVE TO PAY AT THIS POINT. >> AND WE DON'T KNOW WHAT THAT PRICE WOULD BE. NEGOTIATIONS ARE OBVIOUSLY STILL GOING ON. PRESIDENT BIDEN MADE IT A POINT TO SAY PAUL WIELAND'S NAME SEVERAL TIMES DURING HIS ANNOUNCEMENT TODAY, AND HE CONTINUED TO SAY THAT HE WILL NOT STOP, WILL NEVER STOP UNTIL HE GETS PAUL HOME. >> NANCY PELOSI ACTUALLY ALSO REACTED, RATHER, TO GREINER'S RELEASE, SAYING THAT CONGRESS AND THE COUNTRY ARE OVERJOYED. WHAT ELSE ARE YOU HEARING FROM LAWMAKERS THERE? ON THE HILL? YEAH, WE'RE TRYING TO PIECE TOGETHER BY TALKING TO LAWMAKERS AND THERE'S THAT STATEMENT FROM NANCY PELOSI THERE. WHAT THEY KNEW ABOUT THIS GRINER DEAL, WHAT THEIR REACTION IS, AND ALSO WHAT THEIR REACTION IS TO PAUL WIELAND NOT BEING INCLUDED. WE SPOKE WITH SHEILA JACKSON LEE OF TEXAS, CONGRESSWOMAN FOR BRITTANY GREINER'S HOMETOWN OF HOUSTON, WHERE HER PARENTS STILL LIVE. WE ASKED HER ABOUT HER REACTION TO TODAY, HER REACTION WITH THE ADMINISTRATION HAS BEEN PUSHING FOR AND ALSO ABOUT PAUL WIELAND. HERE'S A LITTLE BIT WHAT SHE HAD TO SAY. I FELT THE FACT THAT THEY DIDN'T WANT TO DO ANYTHING THAT WOULD KEEP HER A DAY LONGER AND IT KEPT GOING A DAY AND A DAY. AND THEN THERE WAS A TIME WHEN TWO PERSONS WERE MOVING. WE WERE MOVING WITH THE IDEA OF ADDITIONAL ABILITY TO SWAP ANOTHER PERSON BECAUSE SOMEONE WENT ON TWO TO ONE. WELL, AS I SAID, THIS IS MR. PUTIN WAY. >> SO WHAT SHE'S SAYING THERE IS THAT IN THE SUMMER, RIGHT, THE UNITED STATES GOVERNMENT HAD COME FORWARD AND SAID, WE WILL TRADE YOU, BRITTNEY GRINER AND PAUL WHEELIN FOR VIKTOR BOUT. AND THEN AT SOME POINT BETWEEN SUMMER AND TO NOW, THE DEAL CHANGES TO BECOME JUST BRITTNEY GRINER. THAT'S WHAT BOTH PAUL WIELAND'S FAMILY AND THE WHITE HOUSE HAS SAID WAS THE ONLY DEAL THAT WAS ON THE TABLE. AND SHEILA JACKSON LEE SAYING ER THAT SHE BELIEVES THAT THE REASON WHY THAT HAPPENED IS THAT IT'S MR. PUTIN'S WAY. I SHOULD TELL YOU, IN THE WAY OF CONGRESS REACTION, KEVIN MCCARTHY POISED TO BECOME THE NEXT REPUBLICAN SPEAKER OF THE HOUSE WHEN REPUBLICANS TAKE THE MAJORITY IN JANUARY, SAID THE DECISION NOT TO INCLUDE PAUL WHEELIN IN THIS DEAL WAS, QUOTE, UNCONSCIONABLE KYRA. >> WELL, AND, AARON, WE HEARD FROM THE WHITE HOUSE NOT LONG AGO THAT THEY WERE GIVEN A CHOICE, EITHER BRITTANY OR NO ONE, WHICH IS WHY PAUL WHEELIN IS STILL THERE IN RUSSIA. CLEARLY, THERE WAS A DIFFERENCE BETWEEN WHAT THEY WERE CHARGED WITH, BUT BOTH CHARGED WITHOUT ANY EVIDENCE OF A CRIME AND BOTH BEING UNJUSTLY HELD IN RUSSIA, ACCORDING TO TO PRESIDENT BIDEN. IN THE WHITE HOUSE, SAID THIS WASN'T LIKE THE UNITED STATES HAD A CHOICE HERE. AFTER MONTHS OF NEGOTIATIONS, THE WHITE HOUSE SAID RUSSIA WAS SIMPLY UNWILLING TO GIVE UP PAUL WHEELIN AT THIS TIME. AND WHATEVER NEGOTIATIONS WERE GOING ON IN THE PAST, IN THE LAST COUPLE OF WEEKS, IT TURNED INTO GRINER OR NO ONE, AND THE WHITE HOUSE SAID THEY DID NOT WANT TO MISS AN OPPORTUNITY TO BRING BRITTNEY GRINER HOME. SO THEY WERE WILLING TO TRADE VICTOR BOOT, A HIGH VALUE TARGET WHO HAD BEEN SERVING A TWENTY FIVE YEAR PRISON SENTENCE IN ORDER IN COMING AFTER HIS CONVICTION FOR CONSPIRACY AND INTERNATIONAL ARMS TRAFFICKING. SO THEY WERE WILLING TO TRADE HIM FOR GRINER WHILE THEY SAID THEY WILL KEEP WORKING TO FREE PAUL WHEATLAND AND PRESIDENT BIDEN SAYS THEY WILL KEEP, AS AARON SAYS, FIGHTING TO GET PAUL WHEELIN HOME. BUT BUT WHERE DO THEY GO FROM HERE? WE DIDN'T GET A LOT OF DETAILS ON HOW EXACTLY THEY PLAN ON DOING THAT. BESIDES JUST KEEPING THE PRESSURE ON RUSSIA. NO, HERE, WE PROBABLY WON'T HEAR A LOT OF DETAILS ABOUT THAT. >> I SPOKE TO AMBASSADOR BILL RICHARDSON, WHO HAD A HAND IN BRITTNEY GRINER HAS RELEASED A COUPLE OF MONTHS AGO. AND I ASKED HIM THAT QUESTION AND HE SAID NOT EVERYTHING THAT YOU SEE ON TV OR READ IS ALL THAT'S HAPPENING. THERE IS A LOT OF BACK CHANNEL DISCUSSIONS GOING ON. WE DO KNOW THAT A SENIOR ADMINISTRATION OFFICIAL SPOKE TO PAUL WHEELIN TODAY TO TAKE HIM THROUGH THE NEWS AS IT WAS HAPPENING. AND THEY SAID TO US, THE SENIOR ADMINISTRATION OFFICIAL, DUE TO THE NATURE OF THE SHAM ESPIONAGE CHARGE AGAINST PAUL. AND THAT'S REALLY WHAT RUSSIA IS SAYING, IS THE DIFFERENCE HERE. THE CHARGES ARE DIFFERENT. THEY'RE TREATING THE TWO DIFFERENTLY. AND AS AARON MENTIONED, YOU KNOW, THIS IS THIS IS SORT OF HOW PRESIDENT PUTIN WORKS IN THESE SITUATIONS. SO THE PRESIDENT SAID THEY ARE NOT GOING TO STOP TRYING TO BRING PAUL WHEELIN HOME. HE STILL SEES THAT AS THE GOAL AND WHAT WILL HAPPEN. BUT RIGHT NOW, YOU KNOW, IT'S IT'S IT'S BACK CHANNEL DISCUSSIONS. NOTHING IN PUBLIC. WE'LL STAY ON IT, AARON. PHIL, THANKS, GUYS, SO MUCH. HISTORY TODAY ON CAPITOL HILL. THE HOUSE PASSING THE RESPECT FOR MARRIAGE ACT, WHICH CODIFIES FEDERAL RECOGNITION OF SAME SEX AND INTERRACIAL MARRIAGES. AS ABC NEWS SENIOR POLICY REPORTER AND FLAHERTY REPORTS, THAT BILL IS NOW HEADED TO PRESIDENT BIDEN'S DESK. >> THE HOUSE OF REPRESENTATIVES TODAY PASSING A FEDERAL RIGHT TO SAME MARRIAGE. THAT LEGISLATION PASSING TWO HUNDRED AND FIFTY TO ONE SIXTY NINE. THIS, OF COURSE, COMES AFTER THE SENATE PASSING ITS VERSION OF THE BILL WITH 12 REPUBLICANS SIGNING ON. THAT IS A SIGNIFICANT NUMBER OF REPUBLICANS SUPPORT. OF COURSE, NOW IT GOES TO THE PRESIDENT TO BE SIGNED INTO LAW BY PRESIDENT BIDEN IS EXPECTED TO SIGN THIS NEXT WEEK. THIS IS ONE OF THE MOST SIGNIFICANT CIVIL RIGHTS LEGISLATION, BILLS TO PASS IN PROBABLY SEVERAL YEARS SINCE THE REPEAL OF DON'T ASK, DON'T TELL. >> WHAT THIS BILL DOES IS IT SERVES AS A KIND OF INSURANCE POLICY, A FAILSAFE. IF THE SUPREME COURT WERE TO OVERTURN 20 15 RULING OVER COFELL, THIS WOULD KICK IN. IT WOULD GUARANTEE THAT IF A COUPLE IS MARRIED IN ONE STATE, THAT ANOTHER STATE HAS TO RECOGNIZE THAT UNION IS LEGAL. IT'S A SIGNIFICANT STEP FORWARD TO HAVE THIS FEDERAL RIGHT. ADVOCATES ARE CHEERING THIS. OF COURSE, IT DOES PROVIDE PROTECTIONS TO RELIGIOUS LIBERTY GROUPS, RELIGIOUS GROUPS, AND SAYS THAT THEY CAN KEEP THEIR TAX EXEMPT STATUS. THAT NOTHING IN THIS BILL SHOULD BE USED TO TAKE AWAY GRANT MONEY FOR EXAMPLE. AND BOTH SIDES ARE CHEERING IT ON. I THINK THAT ONE OF THE MOST INTERESTING PIECES OF THIS IS HOW IT CAME TOGETHER BEHIND THE SCENES, GOP DONORS, WEALTHY DONORS CALLING UP REPUBLICAN SENATORS AND SAYING ,YOU KNOW, LET'S GET THIS OFF OF OUR PLATE. LET'S DEAL WITH THIS BEFORE A TWENTY, TWENTY FOUR ELECTION . SENATOR SINEMA ALSO WORKING CLOSELY WITH THE MORMON CHURCH TO GET THIS DONE. SO BOTH SIDES SAYING THIS IS A BIG DEAL, THIS IS A STEP FORWARD IN CIVIL RIGHTS. ALL RIGHT. AND FLAHERTY, THANK YOU SO MUCH . AND COMING UP, SHE SURVIVED THAT DEVASTATING A SCHOOL SHOOTING AND IS NOW ON A MISSION. YOU'LL MEET THIS REMARKABLE, TR. 2020 NOW STREAMING ON "ABC NEWS LIVE" HAVE. >> AND WELCOME BACK TO TRAGEDIES BRINGING FAMILIES TOGETHER LAST NIGHT, THOSE WHO LOST KIDS AND LOVED ONES IN THE SANDY HOOK AND ALL DAY SHOOTINGS GATHERED TOGETHER ON CAPITOL HILL. BOTH JOINED BY THE PRESIDENT AND HOUSE SPEAKER NANCY PELOSI. THEY HONORED THE THOUSANDS OF PEOPLE WHO HAVE DIED DUE TO GUN VIOLENCE. >> AND IT WAS PART OF THE 10TH ANNUAL NATIONAL VIGIL FOR ALL VICTIMS. WITHIN THAT CROWD WAS A VERY SPECIAL LITTLE GIRL, 10 YEAR OLD KAITLYN GONZALEZ. SHE'S ACTUALLY A SURVIVOR OF THE ROBB ELEMENTARY SCHOOL SHOOTING. AND NOW SHE'S CALLING FOR CHANGE. I HAD THE HONOR TO TALK VIGIL AR PUSH TO MAKE A DIFFERENCE. SO 10 YEAR OLD KAITLYN GONZALEZ IS MAKING A DIFFERENCE IN THIS WORLD. AND THAT'S BECAUSE WHAT HAPPENED TO HER IN DUVAL DE TEXAS CHANGED HER WORLD. SHE SURVIVED THAT DEVASTATING MASSACRE. ARAB ELEMENTARY. BUT TWENTY ONE OTHERS DIDN'T, INCLUDING HER BEST FRIEND, NINE YEAR OLD JACKIE CASARES. SO CAITLIN HAS COME HERE TO OUR NATION'S CAPITAL WITH THE HOPES THAT SHE CAN DO EVERYTHING POSSIBLE TO PREVENT ANOTHER COMMUNITY FROM SUFFERING LIKE HERS. CAITLIN WANTS LAWMAKERS TO BAN THE SALE AND POSSESSION OF ASSAULT STYLE RIFLES BEFORE REPUBLICANS TAKE CONTROL OF THE HOUSE OF REPRESENTATIVES THIS JANUARY. SO SHE IS HERE. CAITLIN, IT'S SO GREAT TO HAVE YOU HERE. SO LET ME ASK YOU, WE HAD A CHANCE TO TALK A LITTLE BIT BEFORE THE INTERVIEW STARTED TO TELL ME HOW YOU'RE DOING. JUST HOW YOU'RE FEELING. AND JUST WHEN YOU WAKE UP EVERY DAY, WHAT'S GOING THROUGH YOUR MIND? >> IN YOUR HEART? I'M FEELING GOOD. AND THEN I'M LIKE, SOMETIMES I'LL BE SAD. AND SOMETIMES MOST OF THE 10% HAPPY. >> GOOD. AND YOU'VE BEEN SEEING A COUNSELOR ONCE A WEEK, RIGHT? HOW IS THAT BEEN? DOES THAT MAKE YOU FEEL BETTER? WHAT DO YOU TALK ABOUT AND HOW IS THAT HELPED YOU? OH, WE JUST TALK ABOUT THE GOOD MEMORIES, NOT THE BAD MEMORIES. AND IT'S LIKE IT'S A PAY COUNSELOR. EVERY HOUR SHE'LL PULL ME OUT OF MY CLASS AND SHE'LL GO TAKE ME TO HER OFFICE AND WE WOULD TALK AND CHIT CHAT AND PLAY. >> ISN'T THAT NICE WHEN YOU CAN KIND OF PLAY A GAME, IT HELPS YOU RELAX. THEN YOU HAVE SOMEBODY TO TALK ABOUT YOUR FEELINGS. IT'S IMPORTANT TO TALK ABOUT OUR FEELINGS RIGHT NOW. I CAN I CAN UNDERSTAND THAT. LOOK, EVEN AT MY AGE, WE LOVE TO TALK TO OTHER PEOPLE ABOUT OUR FEELINGS. RIGHT. AND TO GET THROUGH TOUGH TIMES . SO, JACKIE, YOUR BEST FRIEND, YOU LOST HER THAT DAY. >> WHAT DO YOU WHAT DO YOU REMEMBER FROM FROM THAT MOMENT, CAITLIN? >> UM, JUST LIKE CRYING BECAUSE MY MOM HAD TOLD ME THAT SHE HAD PASSED AWAY. SO I WAS JUST I WAS JUST, LIKE, DEVASTATED. DIDN'T I? >> YEAH. WHAT DO YOU MISS THE MOST ABOUT JUST YOUR PERSONALITY AND HER, LIKE, LAUGH AND SMILE. YOU GUYS HAD A GOOD TIME TOGETHER. WHAT WERE YOUR FAVORITE THINGS TO DO TOGETHER? LATER? >> SLEEPOVERS. WE LIKE GOING TO EACH OTHER'S HOUSES. OH, YEAH. MY KIDS LOVE SLEEPOVERS, THAT IS. THEN YOU CAN STAY UP ALL NIGHT, RIGHT. AND TALK ABOUT EVERYTHING AND PLAY GAMES. AND YOUR PARENTS DON'T KNOW WHAT'S GOING ON. I KNOW TOO. I WAS LOOKING AT YOUR BRACELETS AND I ASKED YOU ABOUT THOSE AND I NOTICED YOU HAVE ONE TOO THAT SAYS ELIANA. AND I KNOW YOU HAD A BRACELET FOR FOR JACKIE, BUT IT BROKE. AND YOU'RE GOING TO KEEP MAKING THOSE BRACELETS. BUT TELL ME ABOUT ELIANA AS WELL. SHE WAS ALSO A REALLY GOOD FRIEND, WASN'T SHE? YEAH. AND SO HOW ARE YOU AND YOUR CLASSMATES DOING? DO YOU TALK ABOUT A LOT? DO YOU SOMETIMES COME TOGETHER AND TALK ABOUT THE GOOD MEMORIES TOGETHER? AND WE TALK ABOUT LIKE SOME PEOPLE SOMETIMES, BUT THERE'S TWO THERE'S TWO SURVIVORS HERE IN ROOM 112 IN MY CLASS. AND THEY'LL JUST HAVE A HARD TIME LIKE LAST FRIDAY, WE HAD A FIRE DRILL AND THEN EVERYBODY STARTED FREAKING OUT AND STUFF LIKE, OH, WOW. AND YOU YOU SEE HOW IMPORTANT DRILLS ARE, RIGHT? JUST TO PREPARE AND BE READY. AND I CAN'T IMAGINE HAVING TO HEAR THAT AND PROCESS THAT. BUT, YOU KNOW, YOU ARE HERE IN DC. I MEAN, HOW EXCITING TO COME TO OUR NATION'S CAPITAL FROM UVALDE, WHERE YOU EXCITED ABOUT MAKING THIS TRIP? UM, YES. THIS IS MY THIRD TIME ACTUALLY COMING TO WASHINGTON. BUT, UM, I WAS EXCITED ABOUT THIS ONE BECAUSE, LIKE, THE TWO AND THEN THE MARCH AND THE RALLY AND STUFF LATER. THAT'S RIGHT. AND YOU TELL ME TELL ME WHY YOU CAME THIS TIME. WHAT WHY WAS IT IMPORTANT TO YOU TO COME AND TAKE PART IN THE VIGIL AND JOINING OTHER ADVOCATES FROM UGALDE? UM, THIS IS MY SEVENTH SEVERALS MARCH WITH MARCH 4TH TO DO THE MARCHING TO PASS THE BAND TO BUY AN ASSAULT WEAPON. AND THEN THE VIDEOS JUST TO REMEMBER ALL THE ONES THAT WE LOST RIGHT. YOU'LL NEVER FORGET THOSE FRIENDS THAT YOU LOST. YEAH, THEY'RE SPIRIT. THEIR MEMORY LIVES ON AND FIGHTING FOR CHANGE. YOU WANT THIS BILL TO BE PASSED. YOU'RE FIGHTING TO BAN ASSAULT WEAPONS. YOU KNOW, THAT'S A PRETTY HEAVY THOUGHT FOR A TEN YEAR OLD GIRL. YOU HAVE LEARNED A LOT, HAVEN'T YOU? WHAT HAVE YOU LEARNED ABOUT THESE TYPES OF WEAPONS? AND TELL ME WHY YOU WANT THEM BANNED. >> OH, WELL, THEY BELONG IN A WAR, NOT THE CLASSROOM OR LIKE THE GROCERY STORY. SO THAT'S WHY WE NEED A PACK BAN ASSAULT WEAPONS. AND NOT EVERYBODY RESPECTS GUNS . RIGHT. AND KNOWS KNOWS HOW TO USE THEM AND WHY TO USE THEM AND WHAT THEY'RE FOR. DID YOU FEEL LIKE YOU HAD TO LEARN A LOT ABOUT CERTAIN WEAPONS AND WHY THEY'RE EVEN HERE? >> OH, YES, I DID. BUT I DIDN'T WANT TO. BUT IT'S LIKE YOU HAVE TO IF YOU WANT TO DO THAT, LIKE TAKE THE AVERAGE KITTY. YOU'RE RIGHT. YOU GOT TO KNOW WHAT YOU'RE TALKING ABOUT WHEN YOU'RE BEING AN ADVOCATE, RIGHT?

YOU KNOW, YOU'RE A SPECIAL LITTLE GIRL. YOU'RE DOING VERY WELL IN SCHOOL. I CAN SEE HOW CLOSE YOU ARE WITH YOUR SISTER. AND NOW IT SEEMS LIKE YOU HAVE EVEN A BIGGER, MORE SPECIAL PURPOSE. AND WHAT DO YOU THINK THAT IS? UM, THIS TO BE LIKE AN ADVOCATE AND BE A NORMAL CHILD? ALEX, STUFF LIKE THAT. BECAUSE I WANT TO BE AN ADVOCATE AND LIKE STUFF. AND YOU'RE MY FRIENDS, TOO. BUT THEN I WANT TO BE A NORMAL CHILD LIKE A JUST A REGULAR KID . >> I AGREE. YOU SHOULD HAVE A GOOD BALANCE OF BOTH. I'VE ALREADY READ THAT YOU HAVE CAMPAIGNED WITH DEMOCRATIC CANDIDATES. YOU MET WITH U.S. SENATORS, YOU'VE DELIVERED SPEECHES IN FRONT OF HUNDREDS OF PEOPLE. YOU WERE AT THAT SCHOOL BOARD MEETING ADDRESSING THE POLICE CHIEF, PETE ARREDONDO, WHO IS NO LONGER THERE.
