He was expected to resign after Mueller concluded his investigation into potential ties between Russia and the Trump campaign. In April, Mueller released his 448-page report on his probe.

Flood criticized Mueller in a five-page letter dated April 19 in which he reacted to his final report for not reaching a final conclusion regarding potential obstruction of justice charges against Trump.

“The Special Counsel and his staff failed in their duty to act as prosecutors and only as prosecutors,” Flood wrote, complaining that the report "suffers from an extraordinary legal defect" by failing to comply with the "requirements of governing law."

The report showed Mueller was unable to prove ties between Russia and the Trump campaign. He declined to make a determination about whether Trump committed obstruction of justice.
