Russian dissident and chess champion Garry Kasparov endorsed VP Harris:

“Given my experience, I am not willing to stand idly by and watch the beacon of hope that I am grateful to now call home slide into the authoritarianism of my childhood. This election is a choice between a candidate who has vowed to fight for America’s institutions, and one who is deeply dangerous—a candidate who I believe will bring total mayhem and destruction to this country.”
