Special counsel Robert Mueller has given the Trump Train a shot of rocket fuel, the president's allies say — and now Republicans want to turn that momentum into payback.

President Trump suggested on Monday that he wants new investigations into the workings of the FBI and Justice Department and his political opponents.

Sen. Lindsey Graham, R-S.C., said he wants to know more about "the other side of the story," including former President Bill Clinton's infamous meeting on the airport tarmac with then-Attorney General Loretta Lynch in 2016.

And House Minority Leader Kevin McCarthy, R-Calif, said the chairman of the House intelligence committee, Rep. Adam Schiff, D-Calif., has lost his credibility and should step down from that post.
