Don Brown, a North Carolina Republican candidate for the U.S. Senate, argued that President Donald Trump should use the Insurrection Act to fight what he said was "literal civil war on the streets."

During a Monday interview on Real America's Voice, host Jake Novak asked Brown about Trump's decision to deploy National Guard troops in Portland.

"I just feel like we're in a civil war here in America," Novak said. "I wish, I mean, I'm not trying to be hysterical here, but I don't know what else to call it. It's becoming kinetic. People are dying, literally. I wonder if you're as alarmed as I am?"

"You've nailed it on the head," Brown agreed. "There is a literal civil war on the streets."

The candidate argued that Trump had a duty to "ensure domestic tranquility."

"The President of the United States has the authority to send in the National Guard to these cities where domestic tranquility and rampant crime have taken over, with or without the request from the local authorities," he said. "You look into the Insurrection Act. And when Americans' constitutional rights and liberties are being threatened, the president can go ahead and send in troops."

"The president has the authority to do it. And these local leaders who are soft on crime and pro-crime and just want to kiss up to antifa and all these communist left-wing groups that are intent on unraveling civil society, they're not relevant," he added. "So I'm going to encourage the president to do what he needs to do."

A lawsuit filed by Oregon and the city of Portland asserted that Trump did not have the authority to deploy National Guard troops in response to "small" protests near an Immigration and Customs Enforcement facility.

"There is no insurrection or threat to public safety that necessitates military intervention in Portland or any other city in our state," Oregon Gov. Tina Kotek (D) said in a statement.
