A former White House aide has criticized President Donald Trump's recent social media behavior, calling it "watching his brain rot in real time." Sarah Matthews, who previously served as a deputy press secretary in the Trump administration and left after the January 6 Capitol riot, made the comments to The New York Times. She described how Trump’s frequent posts on his platform, Truth Social, have made the increasingly bizarre content appear normal over time. Matthews noted that Trump spends considerable time consuming and sharing AI-generated content that positions him as the world's most powerful figure. During the Labor Day weekend, Trump posted over 60 times in just 10 hours, many of which were AI-generated images. These included pictures of Trump surrounded by robots, playing the stock market, and a map of the western hemisphere draped in the American flag. Some of the posts were quirky but harmless, such as Trump joking with actor Robert De Niro or posing with George Washington. Others were more provocative, including a doctored image of Trump fighting Canadian Prime Minister Mark Carney on an ice rink and a map suggesting a territorial expansion across North America. Several political figures and commentators have criticized the posts. Maine Democratic Representative Chellie Pingree called the behavior "unhinged" and urged Republicans to address the issue. Ron Filipkowski, an anti-Trump commentator, pointed out the role of Trump’s executive assistant, Natalie Harp, in selecting and approving the content. Some analysts suggested that Trump’s Cabinet consider invoking the 25th Amendment, which allows for the removal of a president who is deemed unfit to serve, citing the posts as evidence of declining mental clarity. MSNBC anchor Lawrence O’Donnell expressed alarm over Trump’s posts, comparing him to King George III and calling him a "deeply sick man." O’Donnell questioned whether the posts were signs of mental instability and urged the media to take Trump’s behavior more seriously. In response, White House spokesperson Davis Ingle defended Truth Social, stating that it gives the president an unfiltered platform to speak directly to the American people, free from what he called the influence of "biased media." Trump's recent posts are part of a long history of controversial online behavior since he returned to the political spotlight. Previously, he has imagined post-war Gaza as a luxury resort, suggested dropping a plane load of excrement on protesters, cast the Obamas as apes, and even portrayed himself as Jesus Christ. His use of AI-generated content has drawn increasing scrutiny, with critics arguing that it reflects a broader pattern of erratic and potentially concerning behavior.
