Lindsey Graham?
Graham saw the dossier when McCain got a copy. He admitted that during his committee hearings with the IG on his report. Maria should ask him why he didn't inform the Trump administration about it. McCain gave the dossier to the FBI. Graham sponsored a resolution supporting the Mueller investigation and that Mueller should not be fired threatening retaliation against Trump. In 2016 Graham proudly announced he was not voting for Trump.
Graham is a snake who is up to his ears on the Russia hoax and Ukraine. On December 30, 2016 President Poroshenko awarded Senator John McCain with the Order of Freedom and presented the Order of Prince Yaroslav the Wise to Senator Lindsey Graham for their significant personal contribution to the enhancement of relations between Ukraine and USA.
