Former Trump campaign official Michael Caputo will go before the House Intelligence Committee July 14.
The private testimony is part of the panel's investigation into Russian interference in the 2016 election and possible ties to President Donald Trump's campaign.
Caputo tells 7 Eyewitness News he's looking forward to testifying to help "move this important process along to debunk the Russia collusion delusion."
Caputo's lawyer, Dennis Vacco, says Caputo has also provided "limited information" to the committee in response to a request.
Caputo lived years ago in Russia, and worked for a period for the Russian-owned Gazprom Media after he returned to the United States.
"I'm a Congressional veteran with 150 House hearings under my belt. I've trained dozens of senior executives to testify before Congress," Caputo says.
Caputo has long denied any wrongdoing.
