The Senate is scheduled to vote on the repeal of the military's "Don't ask, don't tell" law this weekend.

Senate Majority Leader Harry ReidHarry ReidBill O'Reilly: Politics helped kill Kate Steinle, Zarate just pulled the trigger Tax reform is nightmare Déjà vu for Puerto Rico Ex-Obama and Reid staffers: McConnell would pretend to be busy to avoid meeting with Obama MORE (D-Nev.) on Thursday evening called for the end of debate, or cloture, on a standalone bill to repeal the ban on openly gay people serving in the military.

Invoking cloture means that the Senate would take a procedural vote on the repeal legislation on Saturday and a final vote on the bill by Sunday.

Supporters of repeal have at least 60 votes necessary to pass that bill. Several Republicans publicly support it — Sens.

The House already passed the standalone bill on Wednesday. If the Senate passes the bill, it would go to President Obama for his signature, scrapping the 1993 Clinton-era ban.
