The House will vote Wednesday on a standalone bill that repeals the military's ban on openly gay service members with the hopes of forcing Senate action this week. 

Speaker Nancy Pelosi (D-Calif.) announced on her Twitter account that the House will take action one day after the "Don't ask, don't tell" repeal bill was introduced in the lower chamber.

"The House will vote on Rep. Patrick Murphy's standalone #DADT repeal bill tomorrow-Senate action on #DADT is long overdue," reads her tweet.

The standalone bill is widely seen as the last chance Congress has to repeal the ban before the Republicans take control of the House next year. The lame-duck session could end as soon as the end of the week.
