(Reuters) - U.S. President Joe Biden is preparing to propose a major Supreme Court overhaul in the coming week that would include term limits for justices and an enforceable ethics code, the Washington Post reported on Tuesday citing two sources familiar with the plans.

Biden is also weighing whether to call for a constitutional amendment to eliminate broad presidential immunity, the Post reported, adding that Biden discussed at the move in a video conference with the Congressional Progressive Caucus on Saturday.

Biden has previously shunned calls to overhaul the top court with term limits or by expanding the number of seats on the bench. Some Democrats have made calls for the changes following former President Donald Trump's appointment of three conservative justices.

In October, a bipartisan group of legal experts expressed their support for 18-year term limits for Supreme Court justices as a way to deter partisanship and improve the judiciary's reputation.
