Images and video of the new Presidential Walk of Fame were shared on social media, revealing insulting plaques outside the Oval Office after the administration added gilded explanatory markers under presidential portraits.The plaques label Joe Biden with an autopen signature and call him "the worst president," describe Barack Obama as "one of the most divisive political figures in American history" and mock the Affordable Care Act as the "Unaffordable Care Act."Critics say the installation politicizes the White House as the National Trust for Historic Preservation and federal courts weigh a challenge tied to plans to demolish the East Wing for a roughly $400 million ballroom; Karoline Leavitt defended the captions as "eloquently written" and said many were written by the president himself.
