Toobin Urged Mistress to Get an Abortion, Told Her She'd Regret It

Classy guy. I wonder if he sent her flowers for Mother's Day?

Sunday could be a bittersweet first Mother's Day for Casey Greenfield.

Greenfield is a pretty, ginger-haired, Yale-educated lawyer and writer who last March gave birth to a love child. The baby's father is married CNN star and best-selling New Yorker writer Jeffrey Toobin. (Casey's father is esteemed political pundit Jeff Greenfield.) Ever since we broke the news of her pregnancy, Casey has remained silent about the baby drama. But now some of her friends are fed up with what they claim is less-than-gallant behavior on Toobin's part.

Greenfield, now 36, was in her 20s when she fell for Toobin, now 49, even though he was wed to Amy McIntosh, the Harvard sweetheart he'd married in 1986 and who gave him two children.

"Jeff and Casey saw each other off and on over the years," says one source. "She was married to someone else for two years. After her divorce, she started seeing Jeff again. He said he was going to leave his wife for her. But, by then, Casey had begun to distrust him. She suspected he had several other mistresses."

In 2008, when Greenfield became pregnant, and when she told Toobin the news, he offered her "money if she'd have an abortion," says a source. He also allegedly offered to pay for her to have another child later via a sperm donor.

"When Casey wouldn't have an abortion, Jeff told her she was going to regret it, that she shouldn't expect any help from him," claims another source.

Greenfield underwent a risky DNA test while pregnant, but Toobin didn't provide his sample and stopped talking to her, according to sources. On the day she gave birth, Greenfield e-mailed Toobin, inviting him to meet his son, Rory. A source says Toobin didn't reply.

Toobin ultimately cooperated with a DNA test that proved he was Rory's dad. In February, a Manhattan Family Court judge ordered him to pay child support. When he refused to pay the full amount, say sources, Greenfield's lawyer threatened to notify his employers and garnish his wages; Toobin then paid up.
