Concerns about President Joe Biden's cognitive abilities and fitness for office have intensified globally, with multiple sources reporting anxiety among NATO leaders and within the Democratic Party. Former deputy national security adviser KT McFarland and Speaker Mike Johnson have highlighted fears that Biden's perceived lack of control could embolden adversaries like Russia, China, and North Korea. Senate Majority Leader Chuck Schumer and former Speaker Nancy Pelosi have urged Democrats to delay discussing Biden's health until after the NATO summit. Sen. Joe Manchin anticipates a consensus on Biden's candidacy by Sunday, while Rand Paul and J.D. Vance criticize the Democrats' handling of the situation as a threat to democracy. Meanwhile, White House press secretary Karine Jean-Pierre faces backlash for allegedly misleading the public about Biden's health, further straining relations with the press corps.
