Key committee chairs made clear on Monday that they will press the White House for answers about the intelligence assessments, and GOP senators pushed President Donald Trump to exact severe punishments on the Kremlin if the claims are true — even as the president asserts that he was never briefed on the matter.

Ben Sasse (R-Neb.) said. “Number two, what is their plan to make sure that our enemies know that if you target American servicemen and women, the consequences are going to be draconian? And right now, I want to hear their plan for Taliban and GRU agents in body bags.” GRU refers to Russia’s military intelligence agency.
