The GOP-led House Oversight Committee has subpoenaed three senior White House aides—Annie Tomasini, Anthony Bernal, and Ashley Williams—demanding they testify about President Joe Biden's cognitive abilities and overall fitness for office. Chairman James Comer alleges these aides have created a 'protective bubble' around Biden, hindering transparency about his health. The subpoenas follow concerns raised after Biden's poor debate performance and ongoing speculation about his mental state. White House spokesperson Ian Sams has dismissed the subpoenas as a 'baseless political stunt' aimed at generating media attention rather than legitimate oversight. Republicans have also sought testimony from Biden's physician and are continuing investigations into his handling of classified documents and family business dealings.
