After President Joe Biden announced his withdrawal from the 2024 presidential race, two doctors shared insights on his cognitive health with Fox News Digital. Dr. Brett Osborn, a neurosurgeon, suggested Biden showed signs of cognitive impairment for years, which worsened due to stress and past brain surgeries. Dr. Marc Siegel agreed, noting the stress of the campaign could exacerbate cognitive decline. Both emphasized the need for presidential candidates to undergo thorough health evaluations. The White House denied health was a factor in Biden's decision.
