Sen. Thom Tillis, R-N.C., tore into the homeland security secretary at a hearing, saying he will hold up Trump’s nominees until he gets answers from her department.

During a tense public hearing Tuesday, Republican Sen. Thom Tillis called on Homeland Security Secretary Kristi Noem to resign over her handling of the deadly Minneapolis immigration operation.

And he blasted her for killing her dog, which she had described in her memoir as “untrainable,” as well as a goat. Tillis, of North Carolina, argued that killing the animals reflected bad judgment and compared it to DHS’ fatal shootings of two American citizens, Renee Good and Alex Pretti, in Minneapolis.

Then he senator threatened to block many of Donald Trump’s nominees until he gets answers to questions he has posed to the administration about Immigration and Customs Enforcement operations in Charlotte.
