The California Democrat, who was point person for the Democrats as they maneuvered the massive transportation bill to votes, was wrapping up that business when a colleague asked to introduce a visitor to the Capitol.

Sen. Mary Landrieu (D-La.) asked permission to allow Jean-Pierre Bel, the president of the French Senate, to be present in the chamber — a privilege usually only accorded to senators and their designated staffers.

After senators decided that would be just fine, Boxer decided to take her leave — and dropped a little francaise to make her foreign counterpart feel a little more at home.

“With that, I would say au revoir, and I will see everybody in the morning,” Boxer concluded.

At least no one asked for the “ouis and nons.”
