Asked in an MSNBC interview whether Nunes should be investigated, Smith said, “Quite likely, without question."

Another lawyer for Parnas has also told The Daily Beast that Parnas in 2018 helped set up meetings and calls in Europe for Nunes.

Nunes told Breitbart that the accusation was "demonstrably false" and has threatened legal action.

Nunes was the subject of a 2017 investigation over accusations of disclosing classified committee information to the White House but was cleared of that charge, according to Politico. 

The Hill has reached out to Nunes for comment.
