WASHINGTON — The Justice Department is conducting a criminal investigation into former Gov.Andrew Cuomo, a leading contender in the New York City mayoral race, overtestimony he gave to Congresslast year, according to a person familiar with the matter. House Republicans had requested a federal investigation into Cuomo, arguing the New York Democrat lied to the House Oversight Committee in 2024 when he said he had not been involved in reviewing a report from the New York Department of Health about the state's handling of the coronavirus pandemic from when he was governor.

Martin, who revealed on his last day in office that he isfacing an investigation by D.C.'s Office of Disciplinary Counsel, said last week that he planned to"shame" people who the Justice Department didn't charge with crimes— a major departure from DOJ protocol. Early in Trump's second term,several Justice Department officials resignedover the handling of a federal case against New York City Mayor Eric Adams, a Democrat who is now seeking re-election as an independent. Trump administration officials wanted the corruption case against Adams dropped after he began cooperating with the Trump administration on immigration enforcement. Then-Acting Deputy Attorney General Emil Bove said the criminal investigation was hampering Adams' ability to tackle "illegal immigration and violent crime." A federal judge last monthpermanently dismissed the chargesagainst Adams, saying potential future charges couldn't be used as "leverage" over him.
