The U.S. House Oversight Committee, led by Chairman James Comer (R-KY), is intensifying its investigation into President Joe Biden’s capacity to govern, following growing concerns about who was truly running the White House amid Biden’s alleged mental and physical decline. Comer has suggested that subpoenas for Biden family members, including First Lady Jill Biden, may be imminent. If called, Jill Biden would be the first first lady to testify before Congress since Hillary Clinton in 1996.

This move follows testimony from former aides who have refused to answer key questions. Anthony Bernal, former Chief of Staff to the First Lady, reportedly wielded significant influence within the administration. Republican Congressman Byron Donalds (R-FL) expressed that anyone connected to the Biden White House—regardless of their role—should be subpoenaed, naming Jill Biden directly. He criticized Bernal’s limited cooperation, saying his repeated use of the Fifth Amendment raised serious concerns.

Democratic insiders and former DNC officials, including Lindy Li and David Hogg, have labeled Bernal a behind-the-scenes power broker. They allege he and others may have exercised authority on Biden’s behalf without his full knowledge or direction. This allegation is central to the GOP-led inquiry, which questions the legitimacy of executive actions taken during Biden’s presidency.

Of particular interest are the president’s pardons issued in his final days in office. Biden claimed he approved the “standards” for the pardons but didn’t personally sign each one, leading to questions about the use of an autopen and potential staff overreach.

With aides pleading the Fifth and little transparency from the White House, the investigation appears far from over.
