In the ad, which is part of Greitens’campaign for U.S. Senate, released Monday morning, the former governor introduces himself while carrying a large gun. “Today, we’re going RINO hunting,” he says.

The group then enters the home using force with guns in hand.

“Join the MAGA crew, get a RINO hunting permit,” Greitens says. “There’s no bagging limit, no tagging limit, and it doesn’t expire until we save our country.”

Greitens, a sometimes brash outsider whose unconventional resume as a Rhodes Scholar and Navy SEAL officer made him a rising star in Republican politics, abruptly announced his resignation Tuesday, May 29, 2018, after a scandal involving an affair with his former hairdresser led to a broader investigation by prosecutors and state legislators.

Greitens posted a column fromThe Washington Posttitled “Elite Republicans are now openly encouraging political violence” on hisFacebookpage, along with the message “Facebook CENSORED our new ad calling out the weak RINOs. When I get to the US Senate, we are taking on Big Tech.”

Greitens' career in politics has been riddled with controversy dating back to 2018, when he was indicted ona felony invasionof privacy charge related to allegations that he had tried to blackmail the woman with whom he had the affair, though that charge was laterdropped.

Greitens also denied wrongdoing in another 2018 criminal charge for tampering with a computer following claims that he improperly took a donor list from his nonprofit veterans group to help his political campaign.

That year, he wasindictedon a felony charge of computer tampering relating to those allegations, though that charge has also since been dropped.

Faced with possible impeachment proceedings, then-Gov. Greitens resigned in June 2018 but decried “legal harassment” and said he had not “committed any offense worthy of this treatment.”

In March, Greitens ex-wife, Sheena Greitens, accused her ex-husband of “unstable and coercive behavior” that included “physical violence” toward their two young children in an affidavit filed in an ongoing child custody dispute.

The former governor released a statement onTwitterat the time, calling his ex-wife’s claims “completely fabricated, baseless allegations.”
