The US attorney for Oregon said federal agents will not be leaving federal facilities in Portland defenseless as the city remains in the grip of rioters.

A mob of protesters used an angle grinder in order to try to break through a fence protecting the federal courthouse in Portland, Oregon.

'Enough is enough.'

'Elected leaders who refuse to stop them are as guilty of abetting a crime as the driver of the getaway car after a bank robbery.'

'They want to destroy the things that bring us together.'

Democratic Rep. Jerry Nadler of New York said he does not believe antifa is real, but a voice on the ground in Portland knows better.

One person was shot Sunday night as the violence in 'out of control' Portland, Oregon, continued to rage.

'I feel like I need to buy a firearm, because clearly this is going to keep happening.'

Several fires were set in the downtown area, including one at the Alameda County Superior Courthouse.

Oregon's attempt to limit what federal agents can do in Portland while battling rioters has just gone up in legal flames.
