Washington (CNN) If Democrats take back the House, the Intelligence Committee will investigate questions involving Russian money laundering and President Donald Trump's businesses, Rep. Adam Schiff of California said on Tuesday.

Schiff, the top Democrat on the intelligence panel, told CNN's Wolf Blitzer on "The Situation Room" that Russian money laundering is one area he wants to probe tied to Russia's 2016 election interference. Schiff said it's one issue where he didn't know whether special counsel Robert Mueller had been given authority to look into the matter.

"The question, though, that I don't know whether Mueller has been able to answer -- because I don't know whether he's been given the license to look into it -- is were the Russians laundering money through the Trump Organization?" he said.

"And that will be a very high priority to get an answer to. For the reason that if they were doing this, it's not only a crime, but it's something provable," Schiff continued, noting something of that nature is an issue the Russians "could hold over the head" of the President and "that might be influencing US policy in a way that is against our national interest."

Schiff's comments are another sign of the different ways House Democrats intend to investigate Trump if they are in the majority next year.
