A Florida white supremacist was thrown behind bars after threatening on Facebook to take his assault rifle to Walmart.

Richard Clayton was busted near Orlando on Friday for a haunting online boast that said, “3 more days of probation left then I get my AR-15 back. Don’t go to Walmart next week,” ABC News reported.

The post came days after the mass shooting at an El Paso Walmart store that left 22 people dead in what authorities are describing as a racist attack — with the accused gunman saying he targeted “Mexicans.”

Patrick Crusius, the alleged El Paso shooter, posted a racist screed online before the attack, police said.

Despite his post, Clayton, 26, was not on probation when he issued his threat, according to police.

It also wasn’t the first time he’s gone on racist rants online.

“Clayton appears to believe in the white supremacist ideology and has a history of posting threats on Facebook using fictitious accounts,” officials at the Florida Department of Law Enforcement told ABC.

He was charged with intimidation through a written threat and ordered held on $15,000 bond at the Orange County Jail.
