Actress Felicity Huffman has agreed to plead guilty in the college admissions cheating scandal.Court documents made public Monday show Huffman and 12 other prominent parents will plead guilty in the scheme.Huffman was accused of paying $15,000 to have a proctor boost her older daughter's SAT score.Huffman was among 50 people charged in what authorities have described as the biggest college admissions scam ever prosecuted by the U.S. Justice Department.Officials say parents paid an admissions consultant to rig their children's test scores and bribe coaches at elite universities to designate their kids as athletic recruits.Fellow actress Lori Loughlin and Loughlin's fashion designer husband, Mossimo Giannulli, are also charged in the scam. They are not among those who've agreed to plead guilty and haven't publicly addressed the allegations."I am pleading guilty to the charge brought against me by the United States Attorney's Office.I am in full acceptance of my guilt, and with deep regret and shame over what I have done, I accept full responsibility for my actions and will accept the consequences that stem from those actions.I am ashamed of the pain I have caused my daughter, my family, my friends, my colleagues and the educational community. I want to apologize to them and, especially, I want to apologize to the students who work hard every day to get into college, and to their parents who make tremendous sacrifices to support their children and do so honestly.My daughter knew absolutely nothing about my actions, and in my misguided and profoundly wrong way, I have betrayed her. This transgression toward her and the public I will carry for the rest of my life. My desire to help my daughter is no excuse to break the law or engage in dishonesty."
