Pence's former chief of staff hits back at Matt Gaetz, saying he'll likely be 'in prison for child sex trafficking' — in what looks like a growing schism in Trumpworld.

Former Vice President Mike Pence's ex-top aide took a swing on Monday at the embattled Florida congressman Matt Gaetz. Pence's former chief of staff Marc Short suggested that Gaetz would be heading to prison soon because of a federal investigation focused on child-sex-trafficking allegations against him. The remarks were the latest in a back and forth between Trump loyalists and those in the former vice president's camp that points to a growing divide in the Republican Party.
