The Biden administration outlined on Monday the changes it wanted to see in the Supreme Court. Stefani Reynolds/BloombergHouse Speaker Mike Johnson said Biden's Supreme Court proposal was "dead on arrival."Biden's plan includes term limits, a binding code of conduct, and no immunity for ex-presidents.But to get the changes through, Biden would need full Democratic control — or help from Republicans.President Joe Biden's pitch to rein in the Supreme Court is off to a rough start.House Speaker Mike Johnson has already sworn to fight the Biden administration's proposal to overhaul the Supreme Court, calling it "dead on arrival."Biden's proposal, announced in a White House press release on Monday, calls on Congress to make three major changes to the high court: setting up 18-year term limits for all justices, creating a binding code of conduct for those justices, and approving a constitutional amendment that explicitly says former presidents aren't immune from prosecution for crimes committed while in office.Citing "recent ethics scandals" among the court's justices and its recent decisions overturning "long-established legal precedents protecting fundamental rights," Biden wrote that these changes were necessary to "restore trust and accountability" in both the president and the Supreme Court.The court has been a source of frustration for Democrats, with the conservative-led panel handing former President Donald Trump and his allies victory after victory — culminating in a decision that ruled sitting presidents are granted presumptive immunity from prosecution.That ruling snarled the various criminal cases against Trump, who was convicted of fraud in New York and faces allegations of mishandling classified documents and conspiring to overturn the 2020 election.Two of the Supreme Court's conservative justices, Clarence Thomas and Samuel Alito, have also been tied up in scandals.
