President Donald Trump addressed questions on Thursday after a visible bruise appeared on his left hand during appearances in Davos, Switzerland. Trump said the bruise was caused by accidentally hitting his hand on a table and added that his daily aspirin use makes him more prone to bruising.

Trump’s latest public appearances have reignited a storm of speculation after fresh footage revealed recurring bruising and discoloration on both of his hands, sparking questions the White House is struggling to quiet. What began as a simple Christmas Eve sighting has now developed into a full-scale online debate as viewers compare events, zoom in on photos and question why the marks seem to appear, vanish and reappear. Across multiple appearances, Trump has been seen using makeup and even bandages to mask the bruising. While officials continue insisting it’s all the result of “firm handshakes,” that explanation is now facing intense skepticism as new clips. WATCH
