• Actor Brad Garrett said that Ellen DeGeneres bears responsibility for the "toxic" workplace culture of her show
  • "Back to the Future" actress Lea Thompson backed Garrett's statement
  • "The Ellen DeGeneres Show" is under internal investigation over mistreatment complaints from former and current staff

Ellen DeGeneres has been called out by actor Brad Garrett, who has appeared on "The Ellen DeGeneres Show" multiple times, for her "horrible" treatment of people after the talk show host issued an apology to her show's crew.

"The Ellen DeGeneres Show" is currently under internal investigation after several employees came forward with allegations regarding its workplace environment. After DeGeneres's letter to her staff was made public, there were some who did not buy the comedian's apology, including Garrett and actress Lea Thompson.

On Thursday, the "Everybody Loves Raymond" and "Fargo" star commented on DeGeneres' letter, saying that the award-winning host's mistreatment of people is "common knowledge."

"Sorry but it comes from the top @TheEllenShow Know more than one who were treated horribly by her. Common knowledge," he wrote on Twitter, tagging DeGeneres.

Thompson supported Garrett's claim, posting on Twitter Friday, "True story. It is."

Garrett's and Thompson's statements come just a day after DeGeneres sent a letter to her crew addressing the workplace misconduct allegations made against the show, producers and the host in a BuzzFeed News article released earlier this month. 

"On day one of our show, I told everyone in our first meeting that The Ellen DeGeneres Show would be a place of happiness — no one would ever raise their voice, and everyone would be treated with respect. Obviously, something changed, and I am disappointed to learn that this has not been the case. And for that, I am sorry," DeGeneres wrote in the message obtained by The Hollywood Reporter.

"Anyone who knows me knows it’s the opposite of what I believe and what I hoped for our show," she continued. "As we’ve grown exponentially, I’ve not been able to stay on top of everything and relied on others to do their jobs as they knew I’d want them done. Clearly some didn’t. That will now change and I’m committed to ensuring this does not happen again."

Meanwhile, netizens flocked to Garrett's and Thompson's posts about DeGeneres, with several noting that it appeared many in the industry were aware of the talk show host's behavior but chose to keep their silence until the issue went public.

"It's interesting when these situations come out in public, how everyone knew about it but didn't say anything," @Mrdenimleather wrote.

"Loved her show for a while but it became clear quickly she’s extremely narcissistic.  What started out as her loving to help people quickly became 'this is all about me and growing my brand'. Ellen tube, every item given away had her name on it, every bday show was,'" @402Seahawks posted.

"I always felt she was nice to her favorite celebrity friends and just tolerates everyone else ... haven’t been a fan in decades," @FatimaS01815 wrote, pointing out DeGeneres' different treatment of guests.

Earlier this year, comedian Kevin T. Porter also called out DeGeneres, describing the host as "one of the meanest people alive." In a Twitter thread he started in March, he encouraged others to share their not-so-kind encounter with her, promising to match every story with a $2 donation to the LA Regional Food Bank.

Porter's post received many responses from individuals who had interacted with DeGeneres at one point and got a bad impression of the host. Others, however, still had faith in the 62-year-old comedian.

"So she's not super friendly, maybe she's socially awkward or even a diva, she still does a lot of good in the world," one person wrote.

"Yeh I agree, also I think people forget that Ellen does comedy. People misunderstand her jokes and laughs as rude. It is comedy, not rudeness. People are really going overboard with this stuff. Ellen is not as bad a people say," another netizen posted.
