“I don't think you need it,” Trump told Fox News host Jeanine Pirro in an interview airing Saturday on "Justice with Judge Jeanine."

“I know some of the people on those commissions are highly - they're very ethical people, very talented, very smart people,” he continued. “I think, let them just do it. You know, they've been doing it for a long time.”

Trump confirmed he believes the investigation should go forward in “the House, the Senate, the FBI.”

Trump fired FBI Director James Comey earlier in the week. Comey had been leading the bureau's investigation into Russian interference, including allegations that Russia colluded with members of Trump’s campaign during the presidential election.

Trump has strongly denied any involvement.

“There is no collusion,” he said in the interview. “We have nothing to do with Russia and everything else. But there is a question, was it Russia, who was it that went in and tried to hack?”

He said the question will be answered as part of current investigations.

“I’d like to see it quick,” Trump said, but added he wants “to see it done properly.”

“I don't want to be in a position where something took place having to do with Russia or any other country or any other person, who knows, but I don't want to be in a position where it's not done correctly,” he said.
