Republican Sen. John McCain of Arizona on Sunday questioned the president's recent order to send American troops to central Africa, saying the move could put the United States on a slippery slope.
"I worry about, with the best of intentions, that we somehow get engaged in a commitment that we can't get out of," McCain said on CNN's "State of the Union."
This week, President Barack Obama ordered about 100 U.S. military personnel to aid in the hunt and removal of Joseph Kony, head of the Lord's Resistance Army, better known as the "LRA."
In a letter sent to House Speaker John Boehner, Obama said the group "has murdered, raped, and kidnapped tens of thousands of men, women and children in central Africa" and "continues to commit atrocities across the Central African Republic, the Democratic Republic of the Congo and South Sudan that have a disproportionate impact on regional security."
The president said the troops will not use force unless acting in self-defense.
While McCain acknowledged that a humanitarian crisis is taking place in the region, he chided the Obama administration for acting without the approval of Congress and warned against getting too involved.
"I remember Somalia. I remember Lebanon," McCain told CNN's Chief Political Correspondent Candy Crowley. "We've got to be very careful about how we engage. This slippery slope thing could happen there."
