Starting in November 2018, Parnas introduced Rudy Giuliani, the President's personal lawyer, to former and current Ukrainian officials, according to Giuliani.
The request from Congress is the second set of subpoenas linking Giuliani and other Trump affiliates to Parnas.
One of Andre's subpoenas requested employment contracts and correspondence about any work Parnas might have performed, and names Ballard Partners, Trump, and Giuliani as potential employers of Parnas.
Ballard Partners paid Parnas a total of $45,000 in 2018 for client referral fees, according to a person familiar with the arrangement.
Even so, in all of the documents Andre has found about Parnas, none show direct payments to Giuliani, Andre said.
