WATCH: Biden speaks on Supreme Court decision ending affirmative action in college admissions

WASHINGTON (AP) — President Joe Biden said Thursday that he “strongly, strongly” disagrees with the Supreme Court’s decision to strike down the use of affirmation action in college admissions, saying justices unraveled “decades of precedent” as the president stressed that race-based discrimination continues to exist in America.

Watch Biden’s remarks in the player above.

The court’s conservative majority overturned admissions plans at Harvard and the University of North Carolina, the nation’s oldest private and public colleges, respectively.

Chief Justice John Roberts said that for too long universities have “concluded, wrongly, that the touchstone of an individual’s identity is not challenges bested, skills built, or lessons learned but the color of their skin. Our constitutional history does not tolerate that choice.”

Justice Clarence Thomas, the nation’s second Black justice who had long called for an end to affirmative action, wrote separately that the decision “sees the universities’ admissions policies for what they are: rudderless, race-based preferences designed to ensure a particular racial mix in their entering classes.”

Justice Sonia Sotomayor wrote in dissent that the decision “rolls back decades of precedent and momentous progress.”

Echoing her dissent, Biden urged colleges not to let the ruling “be the last word.”

“They should not abandon their commitment to ensure student bodies of diverse backgrounds and experience that reflect all of America,” Biden said from the White House. He said colleges should evaluate “adversity overcome” by candidates.

Both Thomas and Sotomayor, the two justices who have acknowledged affirmative action played a role in their admissions to college and law school, took the unusual step of reading a summary of their opinions aloud in the courtroom.

In a separate dissent, Justice Ketanji Brown Jackson — the court’s first Black female justice — called the decision “truly a tragedy for us all.”

Jackson, who sat out the Harvard case because she had been a member of an advisory governing board, wrote, “With let-them-eat-cake obliviousness, today, the majority pulls the ripcord and announces ‘colorblindness for all’ by legal fiat. But deeming race irrelevant in law does not make it so in life.”

The vote was 6-3 in the North Carolina case and 6-2 in the Harvard case. Justice Elena Kagan was the other dissenter.

Two former presidents offered starkly different takes on the high-court ruling.

Former President Donald Trump, the current GOP presidential frontrunner, wrote on his social media network that the decision marked “a great day for America. People with extraordinary ability and everything else necessary for success, including future greatness for our Country, are finally being rewarded.”

Former President Barack Obama said in a statement that affirmative action “allowed generations of students like Michelle and me to prove we belonged. Now it’s up to all of us to give young people the opportunities they deserve — and help students everywhere benefit from new perspectives.”
