Kathy Griffin: 'I am no longer under federal investigation'

The Secret Service investigated her after her photo scandal.

But according to Griffin, she's now in the clear.

"I am no longer under federal investigation," she tweeted Friday. "The case is closed, I have been completely exonerated. Finally."

ABC News had contacted the Secret Service for comment.

At a press conference in early June, Griffin's attorney, Lisa Bloom said, "The Secret Service has reached out to her ... a comedian ... she has has to retain a criminal attorney ... For the first time in history that we are aware of, the POTUS and his family is personally attempting to ruin a comedian ... Whether or not you get or like her artistic expression, Kathy Griffin has the right to publicly ridicule the president."

But Griffin quickly apologized for the photo, taken by celebrity photographer Tyler Shields, tweeting a video, in which she said, "Hey, everybody, it's me, Kathy Griffin. I sincerely apologize. I am just now seeing the reaction to these images. I'm a comic. I crossed the line. I move the line. Then I cross it. I went way too far. The image is too disturbing. I understand how it offends people. It wasn't funny."

Despite the apology, the Secret Service was not amused. It issued a statement — which did not specifically cite the controversy — saying, "The U.S. Secret Service has a critical mission. It is always unfortunate when people make statements that could be perceived as threats. We don't have the luxury of knowing a person's intent. Each alleged or perceived threat has to be investigated thoroughly, which taxes Secret Service manpower and resources that could be utilized elsewhere."
