“I don’t know them, I don’t know about them, I don’t know what they do,” Trump added. “I don’t know, maybe they were clients of Rudy’s. You’d have to ask Rudy.”

A photograph of Trump smiling with Giuliani and the businessmen, Igor Fruman and Lev Parnas, has been published by various news outlets.

Trump acknowledged Thursday that he may have been photographed with the two men at a fundraiser.

Fruman and Parnas were arrested late Wednesday on charges that they conspired to illegally funnel foreign money to U.S. politicians in order to buy political influence.

The indictment unsealed by federal prosecutors in Manhattan alleges that they and two other defendants “conspired to circumvent the federal laws against foreign influence by engaging in a scheme to funnel foreign money to candidates for federal and state office so that the defendants could buy potential influence with the candidates, campaigns, and the candidates’ governments.”

The indictment unsealed Thursday does not name Giuliani nor does it claim he knew of or was involved in the alleged scheme. But the developments have increased scrutiny on Trump’s personal attorney and the connections between the president’s inner circle and the two businessmen.

Frumas and Parnas, who donated to a political action committee that supported Trump, were arrested at Dulles International Airport Wednesday before attempting to board an international flight with one-way tickets. They made an initial appearance in court Thursday afternoon in Virginia.

Federal prosecutors in Manhattan said during a news conference Thursday that their investigation is ongoing.

CNN reported Thursday that Giuliani’s financial dealings with Frumas and Parnas were being scrutinized by federal investigators.

When asked if he was concerned that Giuliani may be indicted, Trump told reporters that he hoped that wouldn’t be the case. Trump also said he hadn't spoken about the matter with Giuliani.

"I haven't spoken to Rudy about it I will say this, from what I heard ... they said we have nothing to do with it."
