Kony, the leader of the Lord's Resistance Army, remains at large despite a 2005 indictment by the International Criminal Court on more than 30 counts of violations of international law, including war crimes.
The White House announced this week that U.S. military advisers would be deployed in Uganda to help track down members of the LRA.
U.S. Rep. Ileana Ros-Lehtinen, R-Fla., chairwoman of the House Foreign Affairs Committee, said the White House is right to remain committed to finding Kony and the LRA.
"The brutality of Kony's crimes is horrifying, and the U.S. must remain committed to ending Kony's campaign of evil," she said in a statement.
A delegation from the United Nations and African Union last weekend warned officials in Chad about a possible resurgence in violence attributed to the LRA. U.N. officials said renewed pressure on the LRA could prompt the militant organization to go on the offensive.
"Joseph Kony and his circle of thugs continue to wreak havoc and must be held accountable for their crimes against humanity, and immediately brought to justice," Ros-Lehtinen said.
