Hillary Clinton's upcoming memoir says her top aide, Huma Abedin, was left in tears after her husband, former Rep. Anthony Weiner, D-N.Y., was discovered to have sent explicit pictures over text to an underage girl.

"This man is going to be the death of me!" Abedin said, according to an excerpt of Clinton's new book, "What Happened." Clinton also wrote that Abedin was "bursting into tears" at the news.

"Anthony had already caused so much heartache," Clinton added. "And now this."

Abedin was quickly removed from the campaign trail as news of the investigation broke, and was not spotted with Clinton until after Election Day. Still, Clinton said she did not hold Abedin responsible for the controversy surrounding her relationship with Weiner, and maintains her loyalty to her.

"She had done nothing wrong and was an invaluable member of my team," she wrote. "I stuck by her the same way she has always stuck by me."

Excerpts of her memoir were obtained by Radar Online.

An emotional Weiner pleaded guilty in May to exchanging sexually explicit material with a minor, a charge that carries years in prison. He agreed not to appeal any sentence between 21 and 27 months in prison. He was also ordered to register as a sex offender.

"I have a sickness, but I do not have an excuse," the former Democratic congressman said at the time.
