Sen. John Kennedy (R-La.) became the latest member of the Senate Judiciary Committee to send up a warning flare that he could vote against one of Trump’s picks.

Kennedy said that Steven Menashi, nominated for the 2nd Circuit appeals court, could be “Oliver Wendell Scalia” but that he couldn’t vote for him unless he gets a clear picture of how Menashi thinks about legal issues.

“If someone gets mad at that, they need to call somebody who cares, because that is my job and I’m tired of them playing games,” Kennedy said in an apparent opening shot at potential critics.

Menashi tangled with several senators, including Kennedy, during his confirmation hearing over frustration that he was dodging their questions. At one point, Sen. Lindsey Graham (R-S.C.), a close ally of Trump’s who chairs the committee, appeared exasperated with Menashi, warning it is “important that you tell us what you worked on.”
