Sen. Mary Landrieu stops by the women's restroom in the Dirksen Senate Office Building. (Melina Mara/The Washington Post)

When the Loop wrote about the expanding womens’ restroom off the Senate chamber, we had no idea just how important a venue we were talking about.

Forget stuffy conference rooms or even the Senate floor — it turns out that womens’ rooms are where plenty of important conversations happen (and they have nothing to do with primping).

Former Secretary of State Madeleine Albright tells us that she has a framed photograph in her office of herself and then-first lady Hillary Clinton. It was snapped in — you guessed it! — a womens’ bathroom during a visit to Prague. “It was the only time we could talk,” Albright recalls.

And we were reminded of a tweet from Sen. Claire McCaskill (D-Mo.) at the beginning of the congressional session about her first “power” confab with a few of her newly elected colleagues, Sens. Elizabeth Warren (D-Mass.) and Deb Fischer (R-Neb.).

Too funny. First power meeting with E Warren and D Fischer? In the Senators Only Women's bathroom. Gonna need a bigger bathroom.

Hmmm.... maybe if official Washington wants to get more done, the answer could be more bathroom breaks.
