Famed women's rights attorney Gloria Allred is representing the twin sister of the whistleblower at the center of the CIA General David Petraeus scandal which resulted in his resignation from the agency, Breaking Celebrity News is reporting.

As we previously reported, while the four-star Army General was director of the CIA, he wrote a letter supporting the child-custody fight of Natalie Khawam, the "psychologically unstable" twin sister of his good friend Jill Kelley.

According to a statement released by Allred, she and her client will hold a news conference Tuesday in Washington D.C. "to explain the truth about who Natalie Khawam really is, correct misconceptions about her, explain her course of action and comment on Natalie's relationship with General Petraeus and his wife Holly."

Kelley, 37, is the married Tampa socialite who was first alerted the FBI of threatening emails allegedly sent to her by Petraeus' mistress and biographer Paula Broadwell -- a bombshell revelation that led to his resignation as the nation's top spy. (Kelley serves as an unpaid social liaison to MacDill Air Force Base in Tampa, where the military's Central Command and Special Operations Command are located.)
