AUSTIN, Texas (AP) — President Joe Biden decried “extremism” that he says has undermined public confidence in the the U.S. Supreme Court, as he 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. Vice President Kamala Harris who is looking succeed Biden quickly endorsed the proposal. Biden detailed the contours of his court proposal in an address on Monday at the LBJ Presidential Library in Austin, Texas. His calls for dramatic changes in the court have little chance of being approved by a closely divided Congress with 99 days to go before Election Day,
