BUFFALO, NY — There was one more battery of questions for Michael Caputo tonight.

It was at the Buffalo Niagara International Airport.

Caputo had just gotten off a Southwest flight from Baltimore. He had spent a long weekend in DC. He was grilled by the House Intelligence Committee behind closed doors for three-hours Friday. More interviews with news organizations followed.

The final hurdle for Caputo, a few questions from the local news outlets at the airport before he headed home to the Southtowns.

One of the questions, are congressional investigators done with him?

Caputo doesn't think so.

"I think it's just beginning," he said. "I had no indication that The House if finished with me and frankly I’m willing to do all of it, whatever I can do to help them understand that there’s nothing to this."

This is the suspicion that the Trump campaign colluded with Russian operatives to try and influence the outcome of the 2016 presidential election.

After testifying, Caputo told reporters in Washington, "I had no contact with Russians. I never heard of anyone in the Trump campaign talking with Russians. I was never asked questions about my time in Russia. I never even spoke to anybody about Russia. I never heard the word ‘Russia’.”

The House Intelligence Committee wanted to talk with Caputo because his resume overlaps both ends of that allegation. He worked in Russia for year and was, for a time, on the communication staff for the Trump campaign. And Caputo was still with the Trump campaign when three members of the Trump inner circle; son Donald Trump, Jr., son-in-law Jared Kushner and then-Trump campaign manger Paul Manafort met with Russian operative supposedly dangling damaging information on Hillary Clinton.

Seemingly most enthusiastic about the meeting was the future president's son.

“The issue Don Junior ran into was that wasn’t an experienced political operative. He didn’t see the inherent problems or at least the potential problems of this meeting and he decided he wanted to be as helpful as possible to father and therefore fell into the trap,” says Caputo.

Already, Caputo says he's supplied some of the documents requested by congressional investigators. He adds he delivered everything in hopes of proving that in his words allegations of collusion are a delusion.
