A gun violence prevention organization named for the victims of the 2012 Sandy Hook school massacre has dropped Megyn Kelly of NBC as the host of its annual gala amid protests of Ms. Kelly’s upcoming interview with Alex Jones, the conspiracy theorist who says the shooting was a hoax.

Ms. Kelly said on Tuesday that she was disappointed at the decision by the organization, Sandy Hook Promise, to drop her as the host of its Promise Champions Gala, which is scheduled for Wednesday. But she defended her interview with Mr. Jones, which has been the subject of criticism since she announced it over the weekend on Twitter.

“I find Alex Jones’s suggestion that Sandy Hook was ‘a hoax’ as personally revolting as every other rational person does,” Ms. Kelly said in a statement. “It left me, and many other Americans, asking the very question that prompted this interview: How does Jones, who traffics in these outrageous conspiracy theories, have the respect of the president of the United States and a growing audience of millions?”

The statement from Ms. Kelly came after some of the families of the 26 people who were killed in the Sandy Hook Elementary School shooting criticized her interview with Mr. Jones, the host of “The Alex Jones Show” and the operator of the right-wing website Infowars, who has said the shooting was a hoax perpetrated by forces hostile to the Second Amendment.
