Washington (CNN) Former Trump campaign manager Corey Lewandowski called for the special counsel's report to be released to the American public when Robert Mueller has concluded his investigation.

"I don't know Mueller, but he seems to be a man of character. And I hope he has a truthful and honest investigation," Lewandowski told CNN's John Berman in an interview Wednesday on "New Day." "When that investigation comes out, I hope it's made public."

He added, "If the report comes out, the entire thing should be given to the American people. And it should show, and I hope Bob Mueller does it, what also took place on the other side of the aisle."

He referred to the law firm working for then-Democratic presidential nominee Hillary Clinton's campaign and its role funding Fusion GPS for opposition research on Trump. Fusion GPS is the research group that hired the former British intelligence officer Christopher Steele, who compiled the Russian dossier on Trump, as a subcontractor.

Mueller was appointed in May 2017 to investigate Russian interference in the 2016 election and possible collusion between Trump associates and Russians. Trump has denied any collusion with Russia.
