Warren, who had no public events yesterday, again refused an interview request from the Herald, responding to questions instead through a spokeswoman by email. Meanwhile, campaign officials scrambled to address another claim Warren’s made about her life’s story.

“I was the first nursing mother to take a bar exam in the state of New Jersey,” Warren told an audience at the Chicago Humanities Festival in 2011, in a video posted on the CHF website. When asked how Warren knows that, her campaign said: “Elizabeth was making a point about the very serious challenges she faced as a working mom — from taking an all-day bar exam when she was still breast-feeding, to finding work as a lawyer that would accommodate a mom with two small children.”

Winnie Comfort of the New Jersey Judiciary, which administers that state’s bar exam, said there’s no way to verify Warren’s claim. Comfort said women have been taking the New Jersey bar exam since 1895, but she’s not aware their nursing habits were ever tracked.
