As visible in yesterday's Congressional Record, there are a number of uncontroversial motions made by the majority leader which passed by unanimous consent. After the motions pass, he moves to "reconsider the vote by which the resolution is considered and agreed to". Then another senator from his party moves to table that motion, which also passes by unanimous consent. Why would someone move to reconsider a vote which they just won?
Here's one of the resolutions, S. Res. 7
FIXING THE HOUR OF DAILY MEETING OF THE SENATE Mr. McCONNELL. Mr. President, I have a resolution at the desk, and I ask for its immediate consideration. The PRESIDENT pro tempore. The clerk will report the resolution by title. The legislative clerk read as follows: A resolution (S. Res. 7) fixing the hour of daily meeting of the Senate. The PRESIDENT pro tempore. With- out objection, the resolution is consid- ered and agreed to. The resolution (S. Res. 7) reads as follows: S. RES. 7 Resolved, That the daily meeting of the Senate be 12 o’clock meridian unless other- wise ordered. Mr. McCONNELL. I move to recon- sider the vote by which the resolution was agreed to. Mr. DURBIN. I move to lay that mo- tion on the table. The motion to lay on the table was agreed to.
