Most likely she knows the evidence is too damning against her. She knows their is going to be an investigation that will discover the truth. By taking the responsibility now, she looks good.

Finally, her revenge comes tonight with Obama having to answer questions about the incident in front of all the American public. Obama got a 3am phone call, slept through it, listened to the answering machine in the morning, did nothing, and took a plane to Vegas baby!
