I'M WHIT JOHNSON. AS WE COME ON THE AIR TONIGHT, PROTESTS ERUPTING NATIONWIDE, REACTION FROM BOTH SIDES TO THE SUPREME COURT'S LANDMARK RULING OVERTURNING ROE V. WADE. DEMONSTRATORS GATHERING AT THE SUPREME COURT. THOSE IN FAVOR OF ABORTION RIGHTS AT TIMES FACING OFF AGAINST MANY CELEBRATING THE JUSTICES' DECISION. THOSE PROTESTS SPANNING THE ENTIRE COUNTRY TODAY, MOST OF THEM PEACEFUL AS EIGHT STATES ALREADY MOVED TO MAKE ABORTION ILLEGAL. OVERNIGHT, OFFICERS FIRING TEAR GAS TO BREAK UP A LARGE CROWD OUTSIDE THE ARIZONA STATE CAPITOL. AND IN IOWA, POLICE LAUNCHING AN INVESTIGATION AFTER A TRUCK HIT PROTESTERS AT AN ABORTION RIGHTS RALLY IN CEDAR RAPIDS. ONE PERSON TAKEN TO THE HOSPITAL. MANY NOW LOOKING TO THE COURT AFTER THE CONSERVATIVE JUSTICES ENDED CONSTITUTIONAL PROTECTIONS FOR ABORTION. AND JUSTICE CLARENCE THOMAS, IN HIS CONCURRING OPINION, SUGGESTED THE COURT MIGHT NOW RETHINK PRECEDENTS SET BY OTHER LANDMARK RULINGS ON GAY MARRIAGE AND CONTRACEPTION. THOSE WORDS HELPING TO FUEL SOME OF THOSE TAKING TO THE STREETS TODAY. WE HAVE TEAM COVERAGE TONIGHT, AND ABC'S CONGRESSIONAL CORRESPONDENT RACHEL SCOTT LEADS US OFF FROM THE SUPREME COURT. >> Reporter: TONIGHT, THE SUPREME COURT'S DECISION SENDING SHOCK WAVES ACROSS THE NATION. >> MY BODY, MY CHOICE! >> Reporter: FROM COAST TO COAST, THOUSANDS PROTESTING THE END OF THE CONSTITUTIONAL RIGHT TO AN ABORTION. IN LOS ANGELES, DEMONSTRATORS FLOODING THE FREEWAY. OVERNIGHT, A TRUCK DRIVER PLOWING THROUGH A CROWD IN CEDAR RAPIDS, IOWA. POLICE NOW INVESTIGATING. IN ARIZONA AT THE STATE CAPITOL, OFFICERS FIRING TEAR GAS AT PROTESTERS. AND POLICE IN PROVIDENCE, RHODE ISLAND, A POLICE OFFICER, A REPUBLICAN RUNNING FOR STATE OFFICE HAS NOW BEEN CHARGED WITH SIMPLE ASSAULT AFTER HE WAS SEEN PUNCHING HIS POLITICAL OPPONENT AT A PROTEST. BUT OUTSIDE THE SUPREME COURT, CHEERS AND RELIEF FOR THOSE AGAINST ABORTION RIGHTS. >> I HONESTLY CRIED TEARS OF JOY. IT'S BEEN SOMETHING THAT WE HAVE BEEN WAITING FOR FOR SO LONG, AND NOW FINALLY, FOR THE LIVES OF SO MANY OF THE UNBORN TO FINALLY BE PROTECTED AND RECOGNIZE WE DO HAVE THE RIGHT TO LIFE, IT WAS REALLY MOVING FOR ME. >> Reporter: PRESIDENT BIDEN WARNED OF THE DIRE CONSEQUENCES, INSISTING THE RULING PUTS REPRODUCTIVE HEALTH AT RISK. >> Reporter: DO YOU THINK THE SUPREME COURT IS BROKEN, IN YOUR VIEW? >> I THINK THE SUPREME COURT HAS MADE SOME TERRIBLE DECISIONS. >> Reporter: THE LANDMARK DECISION BACKED BY THE CONSERVATIVE MAJORITY, STRIPPING AWAY THE RIGHT TO AN ABORTION AFTER NEARLY 50 YEARS. JUSTICE SAMUEL ALITO WRITING, "ROE WAS EGREGIOUSLY WRONG AND DEEPLY DAMAGING. ROE WAS ON A COLLISION COURSE WITH THE CONSTITUTION FROM THE DAY IT WAS DECIDED." AND JOINING ALITO WERE JUSTICES CLARENCE THOMAS, NEIL GORSUCH, BRETT KAVANAUGH, AND AMY CONEY BARRETT, THREE OF THEM TRUMP APPOINTEES. REPUBLICAN SENATOR SUSAN COLLINS WAS CRITICAL TO PUTTING KAVANAUGH AND GORSUCH ON THE BENCH, SAYING THIS ABOUT KAVANAUGH AT THE TIME. >> HE NOTED THAT ROE HAD BEEN REAFFIRMED 19 YEARS LATER BY PLANNED PARENTHOOD VS. CASEY AND THAT IT WAS PRECEDENT ON PRECEDENT. HE SAID IT SHOULD BE EXTREMELY RARE THAT IT BE OVERTURNED. >> Reporter: NOW SHE SAYS SHE WAS MISLED. IN NOTES OBTAINED BY "THE NEW YORK TIMES," KAVANAUGH APPARENTLY GAVE COLLINS PRIVATE ASSURANCES, CLAIMING HE UNDERSTOOD THE REAL-WORLD CONSEQUENCES AND STATING, I AM A DON'T-ROCK-THE-BOAT KIND OF JUDGE. BUT WITH ROE OVERTURNED, THE IMPACT WAS FELT WITHIN MINUTES. ABORTION NOW ILLEGAL FOR 31 MILLION AMERICANS IN AT LEAST EIGHT STATES, INCLUDING LOUISIANA, WHERE REPRODUCTIVE RIGHTS ADVOCATES SAY THEY ARE WORRIED. >> PEOPLE WILL HAVE TO CARRY A CHILD TO TERM WHEN THEY'RE ALREADY LIVING IN SUBSTANDARD HOUSING, WHEN THEIR CHILDREN ARE NOT GETTING THE BEST EDUCATION, WHEN THEY CAN BARELY FEED THEIR FAMILIES. >> EMOTIONS RAW ON BOTH SIDES. RACHEL SCOTT JOINING US NOW FROM THE SUPREME COURT. RACHEL, RECENT POLLING SEEMS TO INDICATE THIS RULING OVERTURNING ROE V. WADE IS AT ODDS WITH WHERE A MAJORITY OF AMERICANS STAND, SO HOW DO SUPPORTERS OF ABORTION RIGHTS PLAN TO CARRY ON THIS FIGHT IN THE FUTURE? >> Reporter: WHIT, I CAN TELL YOU THAT MANY OF THE PEOPLE GATHERED HERE TODAY ALONG WITH DEMOCRATS HOPE THIS TURNS INTO A DRIVING ISSUE AHEAD OF THE MIDTERM ELECTIONS IN NOVEMBER.
