Microsoft said Tuesday that Russian operatives have in recent weeks intensified their online attacks on Vice President Kamala Harris’ campaign by producing and disseminating videos promoting “outlandish conspiracy theories” aimed at stoking US racial and political divisions.

One of the inauthentic videos, which Microsoft said had been viewed millions of times, claimed to show Harris supporters attacking an attendee of a Donald Trump rally. Another video falsely claimed that Harris paralyzed a young girl in a 2011 hit-and-run accident. Russian operatives promoted the latter story through a website pretending to be a local San Francisco media outlet, Microsoft researchers said.

Both videos were still accessible on X as of Tuesday afternoon, with one post of the video garnering 1.5 million views on its own. CNN has requested comment from the social media platform.
