President Donald Trump is taking a measured approach to filling key administration posts and federal judgeships.

The pace of the president's nominations is prompting some Senate Republicans to urge the White House to send more nominees to the Senate for confirmation.

Politico reported that an unnamed White House source said Trump is focused on selecting the right people rather than moving quickly to fill vacancies.

"Ultimately, we need to have the right people in those positions," the source said. "So, if it's acting for now, so be it. If [it] takes a little while to find that perfect person, then it takes a little while."

More than two dozen federal judgeships remain vacant, along with positions including labor secretary, FDA commissioner, and numerous other administration posts.

Judiciary Committee Chair Chuck Grassley, R-Iowa, said the Senate also bears responsibility for the pace of confirmations.

"Right now, it's hard for me to blame the White House when in the last three executive weeks we were supposed to have meetings to vote judges out, we couldn't have enough members present," Grassley said.

Sen. Tommy Tuberville, R-Ala., said he wants to see more judicial nominees sent to the Senate. "We're running short on time," Tuberville said. "We'd love to get at least one or two of them and get it in the next tranche."

He added that he wants to see "as many as we can get" confirmed to the federal bench.

Trump inherited about 40 judicial vacancies at the start of his second term, fewer than any president since Ronald Reagan. Currently, only 10 judicial nominees are pending before the Senate for 29 vacancies.

Trump is on pace with his first administration in overall confirmations after Senate Republicans changed Senate rules to allow civilian nominees to be approved in groups by a simple majority vote.

Federal judges and Cabinet seats, however, still require individual confirmation votes.

Senate Majority Leader John Thune, R-S.D., encouraged the administration to continue sending nominees.

"I think it's always better to have people in permanent positions rather than temporary," Thune said.

Trump said Wednesday that he was delaying Jay Clayton's nomination to lead the U.S. intelligence community in a bid to force Congress to act on a voter ID bill stuck in the Senate.

Trump said in a social media post just hours before Clayton's scheduled confirmation hearing that he will keep Bill Pulte, a top U.S. housing leader, as acting director of national intelligence.
