Sen. Jack Reed on Sunday urged that President Donald Trump be deposed as part of the special counsel’s investigation into any ties Trump’s campaign had with Russia.

At some point in Robert Mueller’s special investigation, “I think he has to come to the president with a list of questions that only the president can answer,” Reed said on “Fox News Sunday.”


“The president should answer truthfully, under oath, those questions,” he said.

The senator from Rhode Island is the top Democrat on the Senate Armed Services Committee and a member of the Senate Intelligence Committee, which is investigating Russia’s involvement in the 2016 presidential campaign. On Friday, Trump vowed "100 percent" to answer under oath any questions from the special counsel.

Asked whether he had any evidence that the Trump campaign had directly colluded with Russia during the campaign, Reed said there are “questions that have been raised about the involvement of his campaign.”

He said he sees Trump's former national security adviser, retired Lt. Gen. Michael Flynn, as a key focus of the investigation.
