(CNN)A lawyer for an indicted associate of Rudy Giuliani tells CNN that his client is willing to tell Congress about meetings the top Republican on the House Intelligence Committee had in Vienna last year with a former Ukrainian prosecutor to discuss digging up dirt on Joe Biden.
The attorney, Joseph A. Bondy, represents Lev Parnas, the recently indicted Soviet-born American who worked with Giuliani to push claims of Democratic corruption in Ukraine. Bondy said that Parnas was told directly by the former Ukrainian official that he met last year in Vienna with Rep. Devin Nunes.
"Mr. Parnas learned from former Ukrainian Prosecutor General Victor Shokin that Nunes had met with Shokin in Vienna last December," said Bondy.
Shokin was ousted from his position in 2016 after pressure from Western leaders, including then-vice president Biden, over concerns that Shokin was not pursuing corruption cases.
Nunes is one of President Donald Trump's key allies in Congress and has emerged as a staunch defender of the President during the impeachment inquiry, which he has frequently labeled as a "circus." Nunes declined repeated requests for comment.
After the story published, Nunes disputed CNN's report, telling far-right website Breitbart that it was "demonstrably false."
Congressional travel records show that Nunes and three aides traveled to Europe from November 30 to December 3, 2018. The records do not specify that Nunes and his staff went to Vienna or Austria, and Nunes was not required to disclose the exact details of the trip.
Nunes' entourage included retired colonel Derek Harvey, who had previously worked for Trump on the National Security Council, and now works for Nunes on the House Intelligence Committee. Harvey declined to comment.
Bondy told CNN that Nunes planned the trip to Vienna after Republicans lost control of the House in the mid-term elections on Nov. 6, 2018.
"Mr. Parnas learned through Nunes' investigator, Derek Harvey, that the Congressman had sequenced this trip to occur after the mid-term elections yet before Congress' return to session, so that Nunes would not have to disclose the trip details to his Democrat colleagues in Congress," said Bondy.
At the time of the trip, Nunes was chairman of the Intelligence Committee. In January, Democratic Rep. Adam Schiff took over as chairman of the powerful committee, which is now conducting the impeachment inquiry.
