ABC News reports that even members of Congress are feeling the effects of a rule that passengers must remain seated for the first and last half hour of flights into and out of Washington-National airport.

Democratic Rep. Sanford Bishop, flying from Ronald Reagan Washington National Airport to Hartsfield Airport on Delta Flight 1717, got up to go to the bathroom after the mandatory half-hour when passengers must stay seated, but found the lavatories on the airplane occupied, his office and aviation sources said.
Sanford then asked a flight attendant for a cup, and “may” have said he intended to relieve himself, his office said.

He went to a section of the plane between the cockpit and first-class, then urinated into the cup, said Bishop spokesman Selby McCash, who described the congressman as “a very gracious and courtly gentleman.”
