He added that Democrats "have some tools in our toolbox" to block Trump from a recess appointment, which would allow the president to bypass what would likely be a contentious confirmation fight.

"We're ready to use every single one of them, any time, day or night. It's so vital to the future of the republic," Schumer said.

Democrats could prevent the Senate from adjourning in mid-August, which could force Republicans to set up "pro-forma" sessions that would effectively block Trump from being able to name a successor without Senate confirmation.

The Senate held pro forma sessions over the weeklong July Fourth recess.

Schumer said Tuesday that Trump is trying to "bully" Sessions out of office.

"I cannot imagine my friends on the Republican side, and particularly in the Republican leadership ... would be complicit in creating a constitutional crisis," Schumer said.

Schumer's warning comes as Trump appears increasingly frustrated with Sessions for his decision to recuse himself from the Justice Department's investigation into Russia's election meddling and potential contacts between the Trump campaign and Moscow.
