This week is shaping up to be one of the most consequential of President-elect Donald Trump’s transition, as senators prepare to consider as many as eight Cabinet nominees in committee.

Republicans are under fire from Democrats and ethics officials for scheduling confirmation hearings before investigators complete a background examination for each nominee, a precedent that goes back decades. But Sunday, Republican leaders vowed to press ahead, saying there are no plans to change the schedule.

Senate Majority Leader Mitch McConnell (R-Ky.) told CBS’s “Face the Nation” on Sunday that Democrats should “grow up and get past” the election result.

“We confirmed seven Cabinet appointments the day President Obama was sworn in,” he said, noting Republicans were in a comparable position in 2009. “We didn’t like most of them, either. But he won the election,” McConnell said. “So all of these little procedural complaints are related to their frustration at having not only lost the White House, but having lost the Senate.”

ON THE CALENDAR: TRUMP NEWS CONFERENCE, BUDGET VOTE-A-RAMA

It’s been six months since Trump held a news conference, and now, he’s finally expected to submit to open questioning from the press on Wednesday. As our colleague Dan Balz wrote this weekend, the timing means Trump will receive pointed questions about Russian interference in the election — a topic Trump’s team is trying strenuously to avoid.

Complicating matters Wednesday, the Senate will consider its first budget resolution of the new Congress. This means one thing: a vote-a-rama expected to go late into the night, involving dozens of amendment votes, since any senator can offer an amendment on any issue.
