Ex-Biden Chief of Staff Testifies in House GOP Cognitive Decline Probe

Ron Klain, former White House chief of staff for President Joe Biden, voluntarily testified before the House Oversight Committee as part of a Republican-led investigation into Biden's cognitive abilities and age. Klain was described as cooperative, answering all questions without invoking executive privilege or the Fifth Amendment, in contrast to other former Biden aides who refused to answer questions by pleading the Fifth. Committee Chairman James Comer is probing whether Biden's use of an autopen for signing official documents indicates actions taken without the president's full knowledge. Democratic and Republican representatives on the committee acknowledged Klain's credibility and thoroughness in his testimony. Other former Biden aides, including the former first lady's chief of staff and Biden's former White House doctor, were subpoenaed but declined to testify fully. The investigation focuses on concerns about Biden's capacity to fulfill his duties as commander-in-chief amid ongoing political scrutiny.
