Cohen, a member of the House Ethics Committee, pointed to recent indicators that Trump may again be seeking to oust Mueller, after a previous attempt was thwarted by the president's legal team.

"Recent events particularly concern me because it seems the President fears that Mueller is close to revealing findings relevant to his mandate and that ending the investigation is the only way to prevent its public release," he said in a statement Wednesday.
