Brands including 23 and Me, Eloquil, Nature’s Bounty, Keurig and Realtor.com have pulled commercials from the “Hannity” show on Fox News after the network aired an interview with Roy Moore, a Republican senatorial candidate in Alabama, who has been accused of inappropriate relationships with teenage girls when he was in his thirties. Some consumers, in support of the show and/or Mr. Moore, have vowed to boycott Keurig products.
