Last week, the U.N. Security Council passed a resolution to extend its peacekeeping mission in Darfur. The resolution passed overwhelmingly, with all countries in the council voting for it, except for the United States. A U.S. representative did not cast a vote, citing concerns about the wording of the resolution.

"The U.S. abstained in the vote because language added to the resolution would send the wrong message to Sudanese President Bashir and undermine efforts to bring him and others to justice," Alejandro Wolff said. "This council cannot ignore the terrible crimes that have occurred throughout the conflict in Darfur."
