Kathy Griffin defends photo with bloody replica of President Trump's severed head

An apologetic Kathy Griffin took to Instagram Tuesday to issue a mea culpa for participating in a photo shoot that featured her holding up a bloody head resembling President Donald Trump.

Kathy Griffin's latest stunt has backfired spectacularly, drawing ire from progressives and conservatives alike.

Griffin herself shared the video from the shoot on her Twitter feed, while referencing Trump's comments toward Megyn Kelly during the Republican presidential debates. I'm a comic. I crossed the line. I move the line and then I cross it. I went too far.

Griffin has since deleted the video and published an apology in which she says she understands how it upset people. It wasn't amusing, I get it.

She explained that she had taken down the image, and had asked the photographer to do the same.

"I went too far". Hours later, Griffin a video clip from the session. "I made a mistake and I was wrong", she said in video posted to her Twitter account a tweet.

The 56-year-old drew widespread criticism after the photo - shot by famed photographer Tyler Shields who is best known for his highly sexualised and edgy work - was leaked to TMZ.

"I was followed up with a second tweet that read", 2/ OBVIOUSLY, I do not condone ANY violence by my fans or other to anyone, ever!
