U.S. Representative Mike Johnson

Rep. Nancy Mace (R-S.C.) is rapidly becoming a pariah among her Republican colleagues, according to a new CNN report.

In a Wednesday segment, CNN host Jake Tapper detailed how House Republicans, staffers and consultants are all becoming more vocal in their belief that Mace is in the midst of a mental health crisis. He began the segment by noting that two of her Palmetto State colleagues — Sens. Lindsey Graham (R-S.C.) and Tim Scott (R-S.C.) — have publicly distanced themselves from her following Mace's profane outburst at police officers and Transportation Security Administration (TSA) agents who were escorting her to a flight.

"It is never acceptable to berate police officers, airport staff, and TSA agents who are simply doing their jobs, nor is it becoming of a Member of Congress to use such vulgar language when dealing with constituents," Scott wrote in a Tuesday post to his Facebook page.

Tapper then observed that Mace "has since posted dozens and dozens and dozens of times about the incident," including a recent press conference in which she doubled down on berating airport police and TSA personnel over a miscommunication about where to meet her upon her arrival at the airport (they located her within minutes of the mix-up). According to the incident report, Mace called officers "f—— incompetent" and said "this is no way to treat a f—— U.S. representative."

"Did I drop an f-bomb? I hope so. Did I call them incompetent? I hope I did. Because they earned it," Mace said. "So I am not going to apologize for holding people accountable."

Tapper reported that Mace's "outlandish" and "erratic" behavior has also alarmed many of her GOP colleagues in the House of Representatives. Wesley Donehue, who is Mace's former political consultant, tweeted this week that it was "time for Nancy Mace to resign and get the help she needs."

According to Tapper, multiple "House Republican sources" say they "have watched her behavior get increasingly odd" before the dust-up at the Charleston International Airport. He also quoted an unnamed "former senior staffer" for Mace who said that her behavior "went from kind of funny to devastatingly sad in terms of her not getting help and displaying this behavior on a national stage."

"One House Republican tells me that Mace's colleagues are 'totally befuddled with her' and that her actions have become 'a big question' within the conference," Tapper said, adding that the source communicated that "the general feeling is there is something unwell about her. She's really going through a crisis. It's sad."

"In a statement to CNN, Donehue — her former consultant — tells me: 'Over the past two to three years, Nancy Mace has been having a sharp mental decline. I'm no doctor, but that's what I believe,'" Tapper reported.

"'She went from being very reasonable person to being someone who cannot control her emotions,'" Donehue continued, per Tapper. "The House Republican told me that there isn't any real infrastructure for the House Republican leadership to deal with this type of situation."
