President Donald Trump took to Twitter early Sunday morning to thank a Western New York political operative for testifying in the House Russia investigation.

Michael Caputo, a political communications expert from East Aurora and former aide to the Trump campaign, appeared before a U.S. House committee Friday to deny he knew of any contacts between the campaign and Russia. That's something the committee is investigating.

After nearly 3 hours of questioning from members of the House Permanent Select Committee on Intelligence, Caputo told reporters he never met with any Russian officials while he was part of the campaign. He even joked that he didn't like Russian dressing.

"To my knowledge I never spoke about his campaign with anyone remotely associated with the Russian government," Caputo said according to the opening statement he made public.

Caputo has ties to Russia and formerly lived and worked in the country. His name first came up as part of the Russia investigation when a Democratic Congresswoman from California accused him of being Vladimir Putin's "image consultant" in the United States, a charge Caputo denies.
