“President Donald Trump is privately furious with Department of Homeland Security Secretary Kristi Noem for suggesting in her Senate Judiciary Committee testimony on Tuesday that he gave advance approval of a taxpayer-funded $220 million ad campaign contract that was subcontracted to one of her allies,” National Review reports.“The president is frustrated that the embattled cabinet secretary repeatedly suggested under oath that the president was aware of the multi-million-dollar ad campaign — which featured Noem prominently — and approved its release before the agency greenlit the contract, according to a source familiar with the president’s thinking.”“One name he has begun floating this week as a potential replacement: Oklahoma’s junior Sen. Markwayne Mullin.”
