Kathy Griffin apologized late Tuesday for posting a photo of her holding a fake severed head resembling that of President Trump earlier in the day.

"I sincerely apologize," the comedienne said in a 30-second video posted to her Twitter account. She said she "crossed the line" and is "just now" seeing the outpouring of negative reactions to the photo," adding "The image is too disturbing."

Griffin also said she is taking down the image and asked the photographer to do the same.

Throughout the day Tuesday, Griffin was widely condemned for the graphic image, including by Chelsea Clinton, who said the picture is "vile and wrong," and journalists too slammed the gruesome photo.

Griffin seemed to respond to the criticism earlier, claiming the imagery was a reference to Trump's crude "blood" comment during the campaign about former Fox News host Megyn Kelly. "OBVIOUSLY, I do not condone ANY violence by my fans or others to anyone, ever! I'm merely mocking the Mocker in Chief," she said in a tweet.

The Secret Service all but confirmed that it was looking into the photo when it tweeted, "On it!" on Tuesday.

The photographer, Tyler Shields, defended the photo shoot was a work of "art."
