Former New York City Mayor Rudy Giuliani said Thursday he “never ever represented any foreign national” after the FBI raided his apartment and seized his electronic devices earlier this week.

Giuliani, who served as former President Donald Trump’s personal attorney, has reportedly been eyed by federal authorities over whether he illegally lobbied the previous administration in 2019 on behalf of Ukrainian officials and oligarchs while searching for damaging information on Trump’s political rivals, including President Joe Biden, then the leading candidate for the Democratic presidential nomination.
