AUSTIN, Texas (AP) — President Joe Biden said Monday that “extremism” on the U.S. Supreme Court is undermining public confidence in the institution and called on Congress to quickly establish term limits and an enforceable ethics code for the court’s nine justices. He also called on lawmakers to ratify a constitutional amendment limiting presidential immunity.

Still, Democrats hope it’ll help focus voters as they consider their choices in a tight election. The likely Democratic nominee, Vice President Kamala Harris, who has sought to frame her race against Republican ex-President Donald Trump as “a choice between freedom and chaos,” quickly endorsed the Biden proposal.
