Giuliani, who served as former President Donald Trump’s personal lawyer, has been the focus of an investigation concerning his activities in Ukraine. He hasn’t been charged and has denied wrongdoing.
The Times reported that investigators seized Giuliani’s electronic devices, according to one person with knowledge of the matter.
CNN previously reported that investigators late last year had raised the prospect of seeking a search warrant for Giuliani’s communications, but were met with resistance from Justice Department officials in Washington over the strength of their evidence, people familiar with the discussions told CNN.
It is unusual for prosecutors to execute a search warrant on a lawyer, although Manhattan federal prosecutors have done so before, most notably in recent years against another former lawyer for Trump, Michael Cohen.
