The Senate Intelligence Committee's probe into Russia's alleged interference in the U.S. election includes looking into the Michael Flynn issue and is "pretty thorough," according to committee member Sen. James Lankford, R-Okla., on CBS News.
"We've already done about three dozen witnesses and we'll be able to work through the process consistently," Lankford said Wednesday, noting that the committee is getting Flynn's business records. "We're going to go wherever the facts go, that's the key thing."
About the Russia probe, Lankford said three areas were the committee's focus.
"The most obvious one is what did the Russians do to try to interfere in our election? The second one is was there any American involved in helping the Russians into their meddling with our election? The third one deals with classified documents and the leaking of those classified documents," Lankford said.
He said the committee is performing oversight for the FBI's investigation, "making sure they see every document."
Lankford said during the CBS appearance that he was especially concerned that Americans were helping Russia.
"If there's any American that is engaging with a foreign power and our elections, that's a real problem. So as those accusations come up, we've got to clear them up, both for the sake of the president and the presidency. We've got to be able to resolve this issue long term and get the facts out. Right now, there are so many unnamed sources and so many accusations in so many places, this creates instability and churn in the United States."
The senator also mentioned in the interview the report about Jared Kushner wanting to set up a back channel to the Russians.
"We're trying to figure out exactly why, for him in particular, was the reason to have back channels. It's one thing for national security to have back channels. It's another thing for other individuals in the White House. So that's a very reasonable question," Lankford said.
