The actor took to Instagram to share a graphic that features an image of the Twin Towers with the message: “R.I.P the 2,996 Americans who died in 9/11. R.I.P the 1,455,590 innocent Iraqis who died during the U.S. invasion for something they didn’t do.”
The Entourage star also shared the post to Twitter, and the image quickly created a social media firestorm, with many calling the actor “disrespectful” and “classless,” as well as threatening to boycott his movies.
After, Grenier, 39, deleted the post and shared several other images to commemorate the day.
“In challenging moments and times of mourning, we must seek perspectives to help us find peace within our choices forward. #911,” he captioned a photo of Ground Zero after the attack.
His other posts – which were all uploaded without a caption – included a painting of firefighters hoisting up the American flag, a photo of two couples kissing with the Twin Towers in the background and a black-and-white pause symbol meant to look like the World Trade Center.
Aside from deleting the post, Grenier has so far made no comment on the controversy.
On Sept. 11, 2001, Islamic terrorists hijacked American airplanes, flying them into the World Trade Center in New York and crashing another into the Pentagon in Virginia. Though the attack was cited by many as a reason the United States later invaded Iraq, intelligence reports showed no direct link between al-Qaeda and the regime of Iraqi President Saddam Hussein.
