Trump released a video with an image of Biden tied to the bed of a truck. He has used similar images in the past, including a photo of him with a baseball bat.
Trump is facing charges related to hush money payments to porn star Stormy Daniels. He also faces charges of making false statements to a federal grand jury in New York. He is also accused of lying to the FBI about his business dealings in the 1990s and 2000s, which he denies. The White House says it is investigating the video.
