The Washington Post reports that the Prince William County sheriff’s office announced the firing on Saturday. The former deputy said that he didn’t make the comments and that his account was hacked. Prince William Sheriff Glendell Hill said he promptly launched an internal investigation after becoming aware of the comments on Christmas morning.
