Using the account @perma_ben, Ben Mora, a regional field director for Sanders’ campaign based in Michigan, has attacked other Democrats in the field—as well as their family members, surrogates, journalists, and politically active celebrities—in deeply personal terms, mocking their physical appearance, gender, and sexuality, among other things.

Sen. Amy Klobuchar (D-MN), Mora has tweeted, “looks like her name: pained, chunky, [and] confused origin/purpose.” Former South Bend Mayor Pete Buttigieg “is what happens when the therapist botches the conversion,” and his husband, Chasten, Mora predicts, will be “busted for running a meth racket” in 10 years. Sen. Elizabeth Warren (D-MA), a frequent subject of Mora’s private account, is called a “dumb Okie,” “an adult diaper fetishist” who “looks like shit” and who lied about having Native American ancestry “to get into Harvard.”…

After this story was published, Mike Casca, the Sanders campaign’s communications director, told The Daily Beast that “we are running a multiracial, multigenerational campaign for justice where disgusting behavior and ugly personal attacks by our staff will not be tolerated.”

Mora, the Sanders campaign confirmed, has been fired.
