Rep. Devin Nunes claimed twice that Alexandra Chalupa, a former staffer for the Democratic National Committee, “worked with officials at the Ukrainian embassy in Washington, DC, to dig up dirt on the Trump campaign, which she passed onto the DNC and the Hillary Clinton campaign.”

Fact First: Chalupa denied the allegations in a 2017 statement to CNN.

"During the 2016 US election, I was a part-time consultant for the DNC running an ethnic engagement program," Chalupa told CNN. "I was not an opposition researcher for the DNC, and the DNC never asked me to go to the Ukrainian Embassy to collect information.

Multiple representatives from the Clinton campaign and the DNC have denied the charges, as has the Ukrainian embassy. "I ran the opposition press program for the Clinton campaign and I don't know what the hell they're talking about," said Zac Petkanas, a former Clinton staffer.

Republicans, though, have seized on the fact that Chalupa did meet with representatives from the Ukrainian Embassy during the election, meetings that Chalupa says were about an "Immigrant Heritage Month women's networking event" she helped organize in June.
