U.S. Representative Henry Cuellar, D-Texas, is navigating new political challenges as his brother, Webb County Sheriff Martin Cuellar, faces charges of misappropriating county funds. The sheriff's indictment comes months after President Donald Trump pardoned the congressman from federal bribery, conspiracy, and money laundering charges.

Martin Cuellar is accused of using county employees and resources for his private disinfecting business, Disinfect Pro Master, between 2020 and 2022. According to the Department of Justice, he allegedly profited approximately $175,000 from these activities. He faces up to 10 years in prison and a maximum fine of $250,000 if convicted. The indictment alleges that Webb County Sheriff's Office employees handled the daily operations of Disinfect Pro Master from the sheriff's office, managing schedules and equipment for disinfecting services both on and off duty using county resources.

Rep. Henry Cuellar was indicted in July 2023 on accusations of accepting nearly $600,000 in bribes from an Azerbaijan-controlled energy company and a Mexican bank. In December 2023, Trump issued a full pardon, which Cuellar stated provided him with a clean slate to focus on his reelection campaign. He won his primary in March and is set to compete in the general election on November 3.

The Cuellar family's financial dealings have drawn scrutiny in the past. Campaign finance records indicate that Rep. Cuellar's campaign and his leadership PAC have contributed to the political aspirations of his siblings. In 2022, his campaign paid his sister Rosie Cuellar for campaign work and donated to her judicial bid. He also donated to Martin Cuellar's sheriff campaign in 2008 and 2020.

Republican strategists have linked the current legal troubles to a pattern within the family. Christian Martinez, national Hispanic press secretary for the National Republican Congressional Committee, stated that the scandals surrounding Martin Cuellar demonstrate that "the scandals didn't end with Henry. They simply moved down the family tree." He further characterized the situation as a "culture of corruption" within the Cuellar family that has held power in South Texas for an extended period.

Rep. Cuellar last secured reelection in 2022, defeating Republican challenger Jay Furman with 52.8% of the vote.
