Caputo was interviewed behind closed doors on Tuesday as part of the committee’s investigation into 2016 Russian election meddling. He was also interviewed last year by the House Intelligence Committee.

“Your investigation and others into the allegations of Trump campaign collusion with Russia are costing my family a great deal of money — more than $125,000 — and making a visceral impact on my children,” Caputo said in a prepared statement that he delivered at the end of the Senate interview, which was provided to CNN.

“Now I must to move back to Washington, New York City, Miami or elsewhere, just so I can make enough money to pay off these legal bills. And I know I have you to thank for that,” added Caputo, who lives in East Aurora, New York.
