"By the time special counsel Robert Mueller was appointed, the FBI had found no evidence of collusion between the Trump campaign and Russia during the 2016 US presidential election," according to agency lawyer Lisa Page.

So not only had the FBI found no evidence of collusion between the Trump campaign and Russia during 2016 but Mueller was appointed with no crime to investigate.

This would indicate Mueller was chasing ghosts in his witch hunt to implicate a hoax on the American people to make Trump look bad which still continues today.

No wonder Rod Rosenstein has asked to have meetings with Trump---both turned down in the last several weeks.
