Democrats’ efforts to temporarily replace California Sen. Dianne Feinstein on the Senate Judiciary Committee met quick opposition Monday from some Republicans, potentially complicating the plan even as some of President Joe Biden’s judicial nominees remain on hold during her extended medical absence.

Feinstein, 89, last week asked to be temporarily replaced on the Senate Judiciary Committee while she recuperates in her home state from a case of the shingles. The statement came shortly after a member of California’s House delegation, Democratic Rep. Ro Khanna, called on her to step down, saying it is “unacceptable” for her to miss votes to confirm judges who could be weighing in on abortion rights, a key Democratic priority.

Senate Majority Leader Chuck Schumer, D-N.Y., said Monday that he is moving forward and hopes to put a resolution on the Senate floor this week seeking a temporary substitute on the panel. But it’s unclear if Democrats will have the votes.

Republican Sens. Tom Cotton of Arkansas and Marsha Blackburn of Tennessee have both indicated they would object to the resolution, meaning there would be a roll call vote — and Democrats would need at least 10 Republicans to vote with them for approval.

The uncertainty over Feinstein’s status, and over the fate of some of Biden’s judicial nominees, is the latest tangle for Schumer as he navigates his party’s one-seat majority in the Senate. Feinstein’s absence comes as another Democratic senator, John Fetterman of Pennsylvania, has also been on an extended medical leave. Fetterman, 52, returned to the Senate on Monday after checking himself into the hospital in February for clinical depression.

It also comes as once-bipartisan votes on federal judgeships — lifetime appointments, in most cases —have been increasingly steeped in partisanship. While the Judiciary committee has moved some of Biden’s judicial nominees with a handful of GOP votes, Republicans are loath to give approval to a plan that will help Biden place more judges on the bench.

“I will not go along with Chuck Schumer’s plan to replace Senator Feinstein on the Judiciary Committee and pack the court with activist judges,” tweeted Sen. Marsha Blackburn, R-Tenn., a member of the Judiciary panel.

Democrats say the are currently 12 federal judge nominees they have been unable to advance because of Feinstein’s absence. It is unclear how many of the nominees would have Republican support.

It is also unclear how long Feinstein will be away. Her office has not given a timeline for her return.

Schumer said he spoke to Feinstein in recent days, and “she believes she will return soon, She is hopeful of that and so am I.”

Feinstein has been away from the Senate since Feb. 27, just two weeks after she announced she would not run for another term next year. She has faced questions in recent years about her cognitive health and memory, and has appeared increasingly frail. But she has defended her effectiveness.
