Jaime Allman, a host at KDNL-TV and 97.1FM in St. Louis, resigned after his advertisers began boycotting his shows following his vulgar tweet, the Washington Post reported Monday.
The since-deleted tweet rapidly drew criticism, prompting several advertisers to withdraw their support for the show, The Allman Report.
Allman, former spokesman for the St. Louis Archdiocese, also hosts a radio show on KFTK, a conservative station.
On Monday, Sinclair Broadcasting Group confirmed he had resigned and had his show canceled after businesses pulled advertising from his shows as a result.More news: Florida GOP Gov. Rick Scott announces Senate campaign, says Washington is 'broken'

Allman is the latest example of the growing feud between conservative personalities and teen activists that has spread across cable news and social media platforms since the Valentine's Day school massacre in Parkland, Florida, launched a national, student-led movement for gun control.
Among his critics is Fox News host Laura Ingraham who took a week long vacation over her comment that he "whined" about not being accepted to four of his chosen colleges. Democratic State Rep. Stacey Newman, who first called on residents to pressure Allman's advertisers, also said Allman had previously attacked students protesting a local school board candidate who describes herself as a "Confederate", and has a lengthy history of Islamophobic, anti-Semitic, and racist posts on her social media accounts.
Allman initially posted the threatening tweet - which included a reference to sexual assault - in March. As of Monday night, it was not clear whether he would continue to host his radio show.
The company recently came under fire for forcing its news anchors to read promos about "one-sided news stories plaguing our country". The deal still requires the approval of federal regulators.
