Sen. Claire McCaskill (D-Mo.), another Democrat up for reelection next cycle, noted that Democrats can’t complain too much about Trump’s likely nominees because they changed the rules in 2013 to allow executive branch picks to be confirmed with a simple majorities instead of 60 votes.

“All of us are looking at every nominee and I think looking to do a lot of thinking but at the end of the day, we’re the ones that changed the rules to allow a president to get a Cabinet with 51 votes,” she said. “Other than pointing out flaws, it will be very difficult to defeat any of them.”

McCaskill, who survived an election scare in 2012, said she’s not going to take early positions on any of Trump’s personnel choices until he names all of his Cabinet selections.

She warned, however, that she would certainly vote against Kansas Secretary of State Kris Kobach, whose name has been floated to serve as secretary of Homeland Security.
