Sen. Lindsey Graham (R-S.C.) said on "Hannity" that he expects a "stampede" by the House of Representatives to impeach President Trump, declaring that Speaker Nancy Pelosi is "not in charge" of her caucus.

"The radical left is in charge. So, I will expect that there will be impeachment proceedings against President Trump, and the Mueller report to me is vindication of President Trump," he said, adding he "hates" that Trump will have to go through this process, but he believes the end result will be Trump's re-election in 2020.

Though Mueller did not allege a Trump-Russia criminal conspiracy, he did lay out findings on possible obstruction of justice by Trump.

The report states that Trump directed then-White House counsel Don McGahn to remove Mueller in June 2017, but McGahn refused the request, later telling an associate that Trump had asked him to do "crazy s***."

Some House Democrats are pointing to the alleged obstruction as the basis for impeachment proceedings. Graham said the obstruction claims are "bizarre," since Mueller did not point to an underlying crime related to Russian collusion.

Graham, chairman of the Senate Judiciary Committee, went on to lay out a series of issues he intends to investigate pertaining to FISA warrants and the origins of the FBI's Trump-Russia probe.
