Kirsten Gillibrand: I don't know who called me 'porky'

WASHINGTON, Sept. 15 (UPI) -- When Kirsten Gillibrand revealed that some of her male colleagues in the Senate had called her fat, many -- supporters and detractors, both -- pressed her to name names.

But now, the New York Democrat has revealed just why she can't identify this particular older male colleague.

In her new book, Off the Sidelines, Gillibrand recalled getting some unsolicited advice while working out in a gym on Capitol Hill.

"Good thing you're working out, because you wouldn't want to get porky!" he told her, according to the book. Her response: "Thanks, a--hole."

On Monday, the 47-year-old lawmaker explained that she can't name her colleague because she didn't recognize him.

"Some very old congressman," Gillibrand said on Good Day New York. "I had no idea who he was and he felt he was OK to give unsolicited advice."

Gillibrand's excuse might sound far-fetched, but the then-Congresswoman had been in Washington for less than a year at the time of the incident.

Besides, as anyone who has spent time wandering the halls of the U.S. Capitol knows, it can be difficult to distinguish one older gentleman from another: Even though the 113th Congress is the most demographically diverse in history, it's still chock-full of white men.

Of the 535 members of both the House and Senate sworn in this term, 380 are white and male, 41 of whom were 70 or older on Jan. 3, 2013.
