In Texas, the FBI entered and searched the home and campaign office of Democratic Congressmember Henry Cuellar this week. Details about the federal investigation, which involves the Justice Department’s Public Integrity unit, are not yet known, but several news outlets report the raid may be part of a federal probe into a group of U.S. businessmen with ties to the former Soviet republic of Azerbaijan.

This comes just weeks before Texas’s March 1 primary election. Voters in the 28th Congressional District will decide between Cuellar and Jessica Cisneros, who narrowly lost a primary challenge to Cuellar in 2020. Cisneros has been endorsed by the AFL-CIO and Senators Bernie Sanders and Elizabeth Warren. She’s a supporter of Medicare for All and the Green New Deal. Cuellar is pro-gun, anti-choice, and has backed private prisons, drone surveillance and increased border militarization.
