Actress Felicity Huffman, best known for her performance as Lynette Scavo on ABC’s “Desperate Housewives,” will plead guilty in connection with the sweeping college admissions scam that has ensnared a number of wealthy families along with officials at some of the country’s elite universities.

The AP cites federal authorities saying Huffman is part of a group of about a dozen prominent parents who have agreed to plead guilty in the scandal.

“The ‘Desperate Housewives’ star and the other parents will admit to charges in the scheme, which authorities say involved rigging standardized test scores and bribing coaches at such prestigious schools as Yale and Georgetown,” the AP reports. “Huffman, 56, was accused of paying a consultant $15,000 disguised as a charitable donation to boost her daughter’s SAT score. Authorities say the actress also discussed going through with the same plan for her younger daughter but ultimately decided not to.”

The report notes that prominent figures in fields including law, finance, fashion and the food and beverage industry are among the other parents charged in connection with the scandal.

“It’s the biggest college admissions case ever prosecuted by the Justice Department,” the AP reports.

“The consultant, Rick Singer, met with Huffman and her husband, 69-year-old actor William H. Macy, at their Los Angeles home and explained to them he ‘controlled’ a testing center and could have somebody secretly change their daughter’s answers, authorities say,” the AP report adds. “Singer told investigators Huffman and her husband agreed to the plan.”

Authorities have not said why Macy was not charged in the case, the report notes. The AP cites court documents indicating Huffman will plead guilty to a charge of conspiracy to commit mail fraud and honest-services mail fraud.
