In Caputo's closing statement obtained by the Washington Examiner, he said the panel's investigation "forced" his family out of their home and "crushed" his children due to mounting legal costs associated with the inquiry.

"Today, I can't possibly pay the attendant legal costs and live near my aging father, raising my kids where I grew up," Caputo said. "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 accused members of the Senate Intelligence Committee of working together and contributing to the "swamp" - a term often used by President Trump to describe the bureaucracy in Washington, D.C.

This point Caputo illustrated by arguing Daniel Jones, a former Senate Intelligence staffer to Sen. Dianne Feinstein, D-Calif., was one of two sources in a recent McClatchy report about Trump's personal lawyer Michael Cohen - a report that Cohen himself denies.

"But who is McClatchy's second source? It couldn't be Dan; he was the first source ... So who could it be - perhaps one of his former Senate Intelligence colleagues? I mean, you're all in this together. You're the swamp."

Caputo called for an "investigation of the investigators" and said he wanted to know who was "coordinating this attack on President Donald Trump."

"Forget about all the death threats against my family. I want to know who cost us so much money, who crushed our kids, who forced us out of our home, all because you lost an election," Caputo said. "I want to know because God damn you to hell."

Caputo's interview before the panel lasted approximately three hours, according to the Buffalo News. Caputo said that he was asked about approximately 20 people affiliated with the Trump campaign and whether he was aware if they had been in touch with Russian officials.

"My answer for each of them was the same," Caputo said. "There was none."
