White supremacist group, Patriot Front, marched in front of Philadelphia City Hall on Saturday, claiming that the presidential election was stolen and that America needed to be reclaimed, according to NBC 10.

Clashing with onlookers, around 200 members from the group waved both American flags and ones with their group insignias on them while wearing white face coverings and shields.

“They started engaging with citizens of Philadelphia, who were none too happy about what they were saying. These males felt threatened, and, at one point, somebody in their crowd threw a type of smoke bomb to cover their retreat, and they literally ran away from the people of Philadelphia,” said Philadelphia police officer Michael Crum, according to ABC 6.

The Anti-Defamation League said that the group, which is based out of Texas, is “a white supremacist group whose members maintain that their ancestors conquered America and bequeathed it solely to them.”
