Longtime Republican U.S. Rep. Kay Granger of Texas is having "unforeseen health challenges” that have worsened in the final months of her more than two decades in Congress, a statement from her office said Monday.

Granger, 81, missed 279 of the House’s 517 votes in 2024, more than the 278 votes she missed between 1997 and 2006. Her last vote was July 24 on an amendment to reduce the salary of an Environmental Protection Agency official to $1. By contrast, Granger missed only 32 votes in 2023.

The retiring representative, whose last House vote was in July, is suffering from dementia and her son says she moved to a senior living facility.
