Although Lee is considered a liberal Democrat, she has occasionally split with members of her own party throughout her congressional career, especially on foreign policy matters. She voted in favor of limiting military operations in the Federal Republic of Yugoslavia, against authorizing air strikes, and in favor of a Republican-backed plan to completely withdraw U.S. troops from the operation, all in 1999. Lee voted against the Iraq War Resolution in 2002. Lee was one of only 46 Democrats to vote for the Online Freedom of Speech Act of 2005. Lee was one of only 13 Democrats to vote against an emergency supplemental appropriations bill in 2007 which, among other things, funded the war in Iraq but required withdrawal of U.S. forces to begin by October 1. However, Lee voted in favor of overriding President Bush's veto of the measure on May 2. In November 2009 Lee was one of 36 representatives to vote "nay" on House Resolution 867, which condemned the UN's Goldstone Report. Lee voted to withdraw troops from Afghanistan in 2010 and 2011. Lee also voted in favor of similar resolutions involving troop withdrawal from Pakistan and, most recently, Libya. Lee also joined her Republican colleagues, one of 70 Democrats to do so, in voting against a resolution to authorize limited use of force in Libya. Lee was also one of only 36 Democrats to vote in favor of limiting funds appropriated for military operations in Libya.
