Pierre Thomas has more on a warning from the FBI about possible armed protests planned in all 50 states over the next 10 days.
Ed Farrell, the former Deputy US Marshal in Chicago, said regular law enforcement will need National Guard backup at some locations.
"There's obviously a big effort to stop and deter these actors before they become operational, which is going to be big," Farrell said. "They're going to be gathering intelligence on these individuals, they will be surveilling these individuals. And if they're able to get probable cause to arrest them, I would imagine you're going to see some arrests of bad actors. Additionally, I think you're going to see an elevated security presence at all government facilities, they're going to limit access to the buildings, they're going to put up barricades, they're going to close doors. Things to prevent people from coming in during this elevated risk time."
