Meghan McCain took to Twitter Sunday morning to call out "Saturday Night Live" for what she described as a "tone-deaf" joke about the appearance of congressional candidate Dan Crenshaw, who wears an eye patch after losing an eye in combat while serving in Afghanistan.

The comment came from "SNL" comic Pete Davidson during the show's mock newscast, "Weekend Update."

Davidson gave his "first impression" of multiple candidates currently running for office.

"You may be surprised to hear he's a congressional candidate from Texas and not a hit man in a porno movie," Davidson joked when a photo of Crenshaw wearing an eye patch appeared.

"I'm sorry. I know he lost his eye in war... or whatever," Davidson added.

Crenshaw, who is running in Texas' 2nd Congressional district, lost his left eye in an IED blast in 2012 while he was serving in the U.S. Navy. Crenshaw was medically retired in 2016 with two Bronze Stars, the Purple Heart, and the Navy Commendation Medal with Valor. He announced he was running for Congress in 2017.

Davidson's joke about the veteran's appearance quickly came under fire.

McCain, the daughter of the late Sen. John McCain, tweeted a reserved, but condemning response to the segment Sunday morning.

"This is really awful and incredibly tone-deaf and offensive to veterans, their families and all who serve," she wrote. "Come on SNL, do better."

Her father was a Navy pilot who endured more than five years as a prisoner of war in Vietnam. His injuries left him unable to raise his arms above his head.

The National Republican Congressional Committee released a statement demanding Davidson and NBC apologize to Crenshaw.

“Getting dumped by your pop star girlfriend is no excuse for lashing out at a decorated war hero who lost his eye serving our country," NRCC Spokesman Jack Pandol said in reference to Davidson's recent highly publicized break-up with pop star Ariana Grande. "Pete Davidson and NBC should immediately apologize to Dan, and to the millions of veterans and military families who tune in every weekend – because they’re not laughing."

Crenshaw reacted in a tweet of his own Sunday afternoon.

"Good rule in life: I try hard not to offend; I try harder not to be offended," he wrote. "That being said, I hope @nbcsnl recognizes that vets don't deserve to see their wounds used as punchlines for bad jokes."
