Perceived election fraud and other conspiracy theories associated with the presidential transition may contribute to violence with little or no warning, according to the bulletin, which is part of a series of intelligence products to highlight potential domestic violent extremist threats to the Washington, DC, region. "Given that the Capitol complex is currently fortified like a military installation, I don't anticipate any successful attacks against the property," said Brian Harrell, the former assistant secretary for infrastructure protection at DHS. "However, all threats should be taken seriously and investigations launched against those who would call for violence. We continue to see far-right extremist groups that are fueled by misinformation and conspiracy theories quickly become the most dangerous threat to society."
