Floyd's death last week after a fatal encounter with a police officer has led to nationwide protests. In widely circulated video footage, a white officer was seen kneeling on Floyd's neck as Floyd gasped for air and repeatedly groaned, "I can't breathe," before passing out.
Twitter said the video on the president's campaign account was affected by its copyright policy.

The three-minute 45-second video uploaded on Trump's YouTube channel was tweeted by his campaign on June 3.
The clip, which is still on YouTube, had garnered more than 60,000 views and 13,000 likes. The video-streaming platform's parent Google did not immediately respond to a request for comment.
The social media platform has been under fierce scrutiny from the Trump administration since it fact-checked Trump's tweets about unsubstantiated claims of mail-in voting fraud. It also labeled a Trump tweet about protests in Minneapolis as "glorifying violence."
