SAN JOSE, Costa Rica -- President Obama on Friday came close to ruling out the use of U.S. troops in Syria, saying he does not see a situation in which that would make sense for the United States or for the Syrian people.

Speaking at a news conference in a visit to Costa Rica, Obama said that "as a general matter, I don't rule things out as commander-in-chief because circumstances change."

But, he added, "I do not forsee a scenario in which boots on the ground in Syria -- American boots on the ground in Syria -- would not only be good for America but also would be good for Syria."
