Nancy Mace staffers alarmed after latest bizarre acts: 'She's deteriorated'

Rep. Nancy Mace (R-SC) has burned a lot of bridges in her short time in Congress, and her former staffers — even the ones who can't stand her — are worried about her mental health.

The South Carolina Republican made headlines by accusing her ex-fiancé of physical and sexual assault in a "scorched earth" speech on the House floor last February, and then went on a high-profile October meltdown against police officers at the Charleston airport.

Insiders told New York Magazine that they're concerned for her well-being.
