By a 76-22 vote, the measure sponsored by Sen. Jon Kyl, R-Ariz., and Sen. Joseph Lieberman, I-Conn., passed and is seen as encouragement for the White House to expedite its decision, The Washington Post reported Thursday.
The administration is reportedly uncertain whether to declare the entire corps a terrorist organization, or only its elite Quds Force, which U.S. military commanders claim are helping insurgents in Iraq.
Senate Democrats' resolve seemed to be bolstered by this week's speeches in the United States by Iranian President Mahmoud Ahmadinejad in which he said his country would ignore U.N. Security Council resolutions about its nuclear program, the Post said.
Another resolution offered by Sen. Joseph Biden, D-Del., that calls for greater diplomatic efforts with Iraq also passed by a 75-23 vote, the report said.
