Democratic firebrand Maxine Waters is pleading with her supporters not to be baited into a confrontation with a far-right militia group planning a protest at her Los Angeles office on Thursday.

The Oath Keepers, who call themselves the Guardians of the Republic but are labeled 'one of the largest radical antigovernment groups in the U.S. today' by the Southern Poverty Law Center, have issued a call to action to their followers to protest the Democratic lawmaker.

'This is both a protest against Maxine Waters' incitement of terrorism, and a stand FOR ICE and the Border Patrol, as they enforce the perfectly constitutional immigration and naturalization laws of this nation,' the group said in a statement.

The group claims 35,000 members who often dress in military gear and carry military-grade rifles at protests across the country.

Waters asked her supporters not to engage with them.

'I am requesting those individuals and groups planning a counter-protest to not be baited into confronting the Oath Keepers with any demonstrations in opposition — such an occurrence would only exacerbate tensions and increase the potential for conflict,' she said in a statement.

'The Oath Keepers have a history of engaging in violent and provocative behavior,' she added.

The lawmaker also noted the Los Angeles Police Department would have officers on hand to ensure people's safety.

But the group said their protest could go on for weeks.

'This is the launch of an ongoing protest that may go on for several weeks. Other patriotic groups are welcome to join us,' read their statement.

The Oath Keepers are protesting Waters' encouragement to the public to harass members of the Trump administration when they see them.

'If you see anybody from that cabinet in a restaurant, in a department store, at a gasoline station, you get out and you create a crowd and you push back on them, and you tell them they're not welcome anymore, anywhere,' Waters said in June.

She is also a harsh critic of President Donald Trump's 'zero tolerance' immigration policy, which had resulted in children and families being separated at the border.

Oath Keepers had a visible presence in Ferguson, Missouri during the 2014 and 2015 unrest in the city, when members armed with semi-automatic rifles patrolled the streets.

Soon after the Stoneman Douglas High School mass shooting in Parkland, Fla., in February, Oath Keepers' controversial founder Elmer Rhoades called upon 'tens of thousands' of the group's members to form militias to protect U.S. schools.
