MyPillow CEO Mike Lindell announced Monday he filed a lawsuit against voting-machine maker Dominion Voting Systems, seeking over $1.6 billion in damages.

Lindell, a supporter of former President Donald Trump’s claims the election was stolen from him as a result of widespread fraud, is filing a lawsuit in the U.S. District Court for the District of Minnesota to protect free speech and remedy damages that MyPillow claims it has suffered, the CEO announced during a live broadcast on Frankspeech.com, his new social media platform.
