Republican senators are eager to continue pushing through President Donald Trump’s executive branch nominees, but they are increasingly concerned about the slow pace of nominations being sent to the Capitol for the people who will be tasked with much of the nitty-gritty work of government.

“I continue to ask for additional names to come forward, and I’m assured that they will be soon,” Republican Policy Committee Chairman John Barrasso said Tuesday.

The Wyoming Republican, who also serves as chairman of the Environment and Public Works Committee, said Republican senators have asked Vice President Mike Pence during the weekly policy luncheons about the lag in lower-level executive branch nominations — the deputy and assistant secretary types who require Senate confirmation.

“He assures us that there’s a long list coming soon,” Barrasso said.

Committee chairmen say they are ready to act, but there’s not always much to act on.
