Some House Democrats plan to introduce a bill to set an 18-year term limit for Supreme Court justices ending lifetime appointments.
It's a largely symbolic response to the high-stakes battle in Congress over the Supreme Court vacancy left by late Justice Ruth Bader Ginsburg.
The legislation has no chance of passage in the Republican-led Senate.
The proposal comes as Senate Republicans try to fast-track a successor to Ginsburg and preserve a conservative majority for a generation.
The bill will be formally introduced Tuesday.
