Left-wing activist group Media Matters is using scandalous allegations surrounding Alabama GOP Senate candidate Roy Moore as a new weapon in their months-long campaign to oust Fox News host Sean Hannity by pressuring sponsors into pulling their advertisements.

Moore is accused of making sexual contact with a 14-year-old girl while he was a 32-year-old attorney, in addition to pursuing romantic (although not sexual) relationships with other teenage girls around the same time.

Media Matters operatives are smearing Hannity to his sponsors, accusing him of defending child sex abuse. (Hannity has explicitly said that anyone guilty of what Moore is accused of doing has no place in politics.)

Media Matters helped pressure several advertisers into pulling their ads from “Hannity” over the weekend. In one instance, Angelo Carusone, Media Matters’ president, tagged a sponsor of Hannity’s show while claiming that Hannity defends “sexually preying on children.”
