Washington (CNN) President Donald Trump and his campaign promoted a dishonestly edited video on Saturday that wrongly made it seem as if Democratic presidential candidate Joe Biden had accidentally endorsed Trump.

The clip, which was viewed more than 5.8 million times and retweeted more than 34,000 times as of Sunday morning at 10 AM, showed Biden struggling with a line in his Saturday speech in Kansas City, Missouri, then saying, "Excuse me. We can only re-elect Donald Trump."

But the clip was edited to cut out the second part of Biden's sentence. What the former vice president actually said was this : "Excuse me. We can only re-elect Donald Trump if in fact we get engaged in this circular firing squad here. It's gotta be a positive campaign." Biden had called for an end to "negative attacks" in his primary contest with Vermont Sen. Bernie Sanders.
