That same day, CNBC reported that Lev Parnas was willing to testify under oath in Congress that Nunes's aides called off a 2019 trip to Ukraine to dig up more dirt on Joe Biden when they realized he would have to report the trip to Intelligence Committee Chairman Adam Schiff. CNBC reported that Parnas's allegations "potentially implicate Nunes and his committee staff in the same events the committee is currently investigating. Specifically, the monthslong effort by Trump, Giuliani and others to get Ukrainian officials to help them dig up dirt on Biden, and to validate far-right conspiracies about Ukraine and the 2016 election." Nunes, who co-sponsored the "Discouraging Frivolous Lawsuits Act", has a long history of filing frivolous lawsuits.
