Federal Investigators Execute Search Warrant at Rudy Giuliani’s Apartment

Prosecutors obtained the warrant as part of an investigation into whether Mr. Giuliani broke lobbying laws as President Trump’s personal lawyer.

Federal investigators in Manhattan executed a search warrant on Wednesday at the Upper East Side apartment of Rudolph W. Giuliani, the former New York City mayor who became President Donald J. Trump’s personal lawyer, stepping up a criminal investigation into Mr. Giuliani’s dealings in Ukraine, three people with knowledge of the matter said. One of the people said the investigators had seized Mr. Giuliani’s electronic devices. Executing a search warrant is an extraordinary move for prosecutors to take against a lawyer, let alone a lawyer for a former president, and it marks a major turning point in the long-running investigation into Mr. Giuliani.
