"Devin Nunes did not go to Vienna or anywhere else in Austria in 2018," declares the lawsuit seeking $435 million in damages. He said he visited two countries: Libya and Malta on a congressional delegation, or "codel."

The CNN story said Mr. Nunes supposedly met with former Ukrainian chief prosecutor Viktor Shokin.

"Devin Nunes has never met Viktor Shokin," says the complaint, filed in U.S. District Court in Richmond. "This meeting never took place. Viktor Shokin doesn't know and hasn't even heard of Devin Nunes."

CNN also reported that Mr. Nunes began communicating with Lev Parnas around the time. He is a Soviet-born U.S. citizen and Florida businessman who became a source for Rudolph W. Giuliani, President Trump's personal attorney. Mr. Giuliani was investigating Ukraine's involvement in the 2016 election
