The compromise came after Reid invoked a procedural measure to block Sen. Rand PaulRandal (Rand) Howard PaulCongress set for clash over surveillance reforms Senate braces for fight over impeachment whistleblower testimony Pelosi names first-ever House whistleblower ombudsman director MORE (R-Ky.) from adding an amendment to Postal Service reform bill that would have cut off American funding to Egypt. Reid said Paul's amendment was too broad. Paul's amendment did not make the list of 39 that Reid announced.

"We tried something a little different here," Reid said Thursday. "Maybe it's not as far as everyone wants to go but it's a pretty good step in the right direction. Rather than having no amendments, rather than having only germane amendments, we decided on having a standard that's very very broad."

Reid said the agreement allowed senators to propose "many different things."

"It gives senators wide range," Reid said.

Reid also announced that the Senate would reconvene on Monday at noon. The Senate will devote two hours of Monday and two more on Tuesday on a vote over a motion to proceed on a GOP resolution disapproving on a National Labor Relations Board rule on election procedures. The disapproval resolution, S.J.Res. 36, follows an announcement by the board in December to amend rules in a way that it said would help expedite union elections. The rule change takes affect April 30.

The Senate adjourned shortly after Reid's announcement, and will return Monday at noon.
