WASHINGTON (AP) — Call it the historic Senate session that wasn't.

The Senate was supposed to officially meet outside the Capitol building for only the second time in almost two centuries on Tuesday but a last-minute move by the rival House scotched plans for a 30-second pro forma session.

Instead, plans to meet in an adjacent Senate office building — to meet the constitutional requirement to meet at least every three days in cases when the House and Senate haven't mutually agreed to adjourn — were scrapped at the last minute.

But it turned out that the House, which was unable to pass an official adjournment resolution because members didn't want to appear like they were abandoning Washington with so much work undone, did so just before the Senate was to meet.
