McHenry posted an apology on Twitter, saying she allowed her emotions to get away from her during a stressful situation at a Virginia business. "I ... said some insulting and regrettable things."
"As frustrated as I was, I should always choose to be respectful and take the high road. I am so sorry for my actions and will learn from this mistake," she wrote.
On the roughly one-minute long video that was captured by a surveillance camera, McHenry says to an employee at a register: "I'm in the news, sweetheart. I will (expletive) sue this place."
The employee tells McHenry she's being recorded, but it doesn't stop her from continuing her rant.
"That's why I have a degree and you don't," she says. "I wouldn't work at a scumbag place like this. Makes my skin crawl even being here."
Later McHenry says, "maybe if I was missing some teeth they would hire me, huh?"
The employee apparently says something about McHenry's hair and the color of her roots.
McHenry sasses back, saying, "Oh, like yours, 'cause they look so stunning, 'cause I'm on television and you're in a (expletive) trailer, honey. Lose some weight, baby girl."
The edited video was first posted on the website LiveLeak
, which said the incident occurred April 5.
The video inspired the Twitter hashtag #firebrittmchenry.
The reporter is one of several ESPN on-air talents to be suspended in the past 12 months.
In February, anchor Keith Olbermann was not on the air for most of a week after a Twitter spat that the anchor had with fans of Penn State University. Bill Simmons was suspended in September for three weeks for calling NFL Commissioner Roger Goodell a liar. Commentator Stephen A. Smith was suspended in July for a week for widely criticized remarks about domestic abuse that referred to possible "provocation" by victims.
With ESPN just one year
McHenry is based in Washington and the incident happened across the Potomac River in Arlington.
McHenry joined ESPN in 2014. At the time of her hiring, ESPN's senior vice president and director of news, Vince Doria, praised her knack for getting interviews with major sports celebrities.
"In a relatively short time, Britt has established a reputation for strong, aggressive reporting in the D.C. area, and an ability to land big interviews," said Doria. "Her presence there will be a great benefit to ESPN's newsgathering and, as with all of our bureau reporters, she will be assigned to high-profile stories around the country."
Before ESPN, she was with WJLA in Washington. McHenry joined the station in 2008 and the sports staff in 2010.
She went to Stetson as an undergraduate and Northwestern for graduate studies in journalism.
Advanced Towing sent CNN this statement regarding the incident:
"Parking enforcement is contentious by nature. At the same time, neither Gina, our lot clerk, nor our company, have any interest in seeing Britt McHenry suspended or terminated as a result of her comments.
"Ms. McHenry is our neighbor, and, as she said, to paraphrase, made remarks that were out of line. She is human and errors in judgement can be made in the heat of the moment.
"Gina is a single mother of 3 children who works a difficult job to provide her family. Gina holds no ill will toward Ms. McHenry.
"As a small business, we saw no benefit to releasing the video, except to highlight personal attacks employees in jobs like towing, public parking enforcement and others sometimes encounter. The video was not licensed or sold to anyone."
