Federal investigators in Manhattan executed a search warrant on Rudy Giuliani’s Upper West Side apartment Wednesday afternoon. Sources say that investigators seized Giuliani’s electronic devices in regard to his dealings with Ukraine.

The New York Times reports:

The investigation of Mr. Giuliani grew out of a case against two Soviet-born men who aided his mission in Ukraine to unearth damaging information about Mr. Biden and his son Hunter, who was on the board of a Ukrainian energy company. The prosecutors charged the two men, Lev Parnas and Igor Fruman, with unrelated crimes in late 2019 and a trial is scheduled for October.

While investigating Mr. Giuliani, prosecutors have examined, among other things, his potential business dealings in Ukraine and his role in pushing the Trump administration to oust the American ambassador to Ukraine, which was the subject of testimony at Mr. Trump’s first impeachment trial.

As part of the investigation into Mr. Giuliani, the prosecutors have explored whether he was working not only for Mr. Trump, but also for Ukrainian officials or businesses who wanted the ambassador to be dismissed for their own reasons, according to people briefed on the matter.

The Manhattan U.S. Attorney’s Office and the F.B.I have been attempting to secure a search warrant for Giuliani’s apartment and phone for months now.
