"Black Insurrectionist,” the anonymous social media persona behind some of the most widely circulated conspiracy theories about the 2024 election, can be traced to a man from upstate New York.

He’s also white.

With a profile photo of a Black soldier and the tagline “I FOLLOW BACK TRUE PATRIOTS,” the account on the platform X amassed more than 300,000 followers while posting dubious claims about Vice President Kamala Harris and her running mate, Minnesota Gov. Tim Walz. Some were amplified by former President Donald Trump, his running mate Ohio Sen. JD Vance, and their Republican allies in Congress. The most salacious claims have come in the closing weeks of the campaign.
