Patel cleared the Senate Judiciary Committee last week by a 12-10, party-line vote and is set for consideration by the Republican-controlled Senate on Thursday afternoon.
He is expected to be confirmed unless more than three Republican senators defy Trump's will and vote against him, which is seen as unlikely. Trump has already secured approval for most of his nominees despite initial Republican skepticism to several of his choices.
The Justice Department in the last month has forced out a group of senior FBI officials and has demanded the names of thousands of agents who participated in investigations related to the Jan. 6, 2021 riot at the U.S. Capitol.
Trump has said that he expects some of those agents will be fired.
Republicans angry over what they see as law enforcement bias against conservatives during the Biden administration, as well as criminal investigations into Trump, have rallied behind Patel as the right person for the job.
