Lawmakers were divided Sunday on whether to support President Barack Obama's call for military action in Syria.
Obama announced Saturday he believes the United States should take limited action, but he pledged to seek approval from Congress first.
Supporters of a military strike said Sunday the U.S. must send a message to Syria and other countries that the use of chemical weapons will not be tolerated. Opponents argued the U.S. should pursue more diplomatic channels rather than position itself in yet another overseas military conflict.
