White House: Biden Won’t ‘Underestimate Trump’ If He Runs for President Again White House chief of staff Ron Klain said President Joe Biden will not “underestimate” former President Donald Trump if he runs for president in 2024. While Trump hasn’t publicly said he would run for president, he’s toyed with the idea in recent interviews and suggested he would make a decision following the 2022 midterm elections. “I wouldn’t want to estimate or underestimate Donald Trump as an opponent if he chooses to run,” Klain told Axios on May 9. “My experience … is that incumbent presidents are judged on their record,” he said, adding that Biden “is hopefully assembling a powerful record to run on if he runs for reelection in 2024.”
