Parnas's comments to The Daily Beast come after he turned over a trove of documents and text messages to House investigators as evidence for impeachment, and made a slew of new allegations in his Wednesday MSNBC appearance.

The documents say Giuliani was acting with Trump’s “knowledge and consent” to pursue a shadow foreign policy, with a letter signed by Giuliani asking for a meeting with Zelensky and with the approval of Trump.

Parnas also claimed in his interview that the president threatened to withhold all aid from Ukraine if it did not publicly announce an investigation into the Bidens, and also implicated other figures including Vice President Pence and Attorney General William Barr Bill BarrBarr says Ginsburg 'leaves a towering legacy' Republicans call for DOJ to prosecute Netflix executives for releasing 'Cuties' Trump doesn't offer vote of confidence for FBI director MORE.

The interview sent shockwaves through Washington, D.C., with Democrats arguing it proves the need for impeachment, while Trump allies insist Parnas is an unreliable source.
