WASHINGTON — The Justice Department is expected to announce the indictment of longtime Rep. Henry Cuellar, D-Texas, on Friday, two sources familiar with the matter told NBC News.Cuellar’s home and campaign office in Laredo, Texas, were raided in January 2022 as part of a federal investigation into Azerbaijan and a group of U.S. businessmen who have ties to the country, law enforcement said at the time. His office had pledged to cooperate with the investigation. In April, Cuellar's lawyer, Joshua Berman, told some news outlets that federal authorities informed him he was not the target of the investigation.
