Sen. Rand Paul (R-Ky.) plans to introduce legislation to repeal the use-of-force resolution that paved the way for the Iraq war.

Paul aims to prevent American troops from being deployed to Iraq again without Congress re-authorizing it. His effort comes amid increasing sectarian violence in Iraq. The Washington Post's Liz Sly reports:

An eruption of violence in Iraq is threatening to undo much of what U.S. troops appeared to have accomplished before they withdrew, putting the country’s stability on the line and raising the specter of a new civil war in a region already buckling under the strain of the conflict in Syria.

From Yahoo's Olivier Knox:

Paul's announcement came one day after Yahoo News reported the White House now favors scrapping the Authorization for the Use of Military Force in Iraq, signed into law in late 2002 by then-President George W. Bush.

Paul has been seeking Senate co-sponsors, and hopes Obama’s decision to support repeal will clear opposition from Democrats and some prominent Republicans.

“This bill will ensure that our chapter of action in Iraq is officially closed, and that any future President seeking to engage in the region will be required to come to Congress to gain authorization and support, as is Constitutionally required,” Paul wrote in a letter to colleagues obtained by Yahoo News.

Paul has attempted to do this before, through the amendment process. A similar measure got 30 votes in November 2011.
