House Members and staff are facing the prospect of walking all the way to the other side of the chamber to send a letter.

All five House-side post offices were named Monday among 19 considered for closure around the District of Columbia, including the office in the Capitol itself. If they all close, that would leave just two post offices for Members: Those in the Dirksen and Russell Senate office buildings.

The cash-strapped U.S. Postal Service is looking at closing the offices in the Ford, Cannon, Longworth and Rayburn House office buildings, according to a posting on its website.

Facing sagging revenues, the agency is considering closing 3,653 locations around the country. The agency has not turned a profit since 2006.

But the Capitol closures are far from a done deal, said Postal Service spokeswoman Sue Brennan.

The locations appear “on a computer-generated list that searched for specific criteria like light foot traffic and low revenue,” Brennan said. “The list simply begins a study process.”

Other locations on the D.C. list include the Pentagon, the Department of Agriculture and the State Department.
