“Sen. Thom Tillis (R-NC) threatened Tuesday to use aggressive procedural measures to bring Senate work to a standstill if Homeland Security Secretary Kristi Noem fails to respond to his offices’ inquiries about an immigration crackdown in Charlotte, North Carolina,” Politico reports.“An irate Tillis, who is retiring this year from the Senate, ripped into Noem during her testimony before the Senate Judiciary Committee on Tuesday, saying that he would use his power as a senator to hold nominations and prevent bills from getting to the Senate floor.”Said Tillis: “If I don’t get an answer that you’ve had a month to respond to, and the remaining ones … as of today, I’ll be informing leadership that I’m putting a hold on any en bloc nominations until I get a response, and in two weeks, if I don’t get a response, I’m going to deny quorum and markup in as many committees as I can until I get a response.”
