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.

Sen. Rand Paul, R-Kentucky, said Sunday the United States should avoid military involvement in Syria. He challenged Secretary of State John Kerry on his assertion America should launch a strike.
"He's famous for saying, 'How can you ask a man to be the last one to die for a mistake?' I would ask John Kerry, 'How can you ask a man to be the first one to die for a mistake?'" Paul said on NBC's "Meet The Press."

Blood and hair samples from eastern Damascus, Syria, have "tested positive for signatures of sarin" gas, Secretary of State John Kerry said Sunday, arguing that with "each day that goes by, this case is even stronger."
Kerry said on CNN's "State of the Union" that the U.S. obtained the samples "independently" through an "appropriate chain of custody," giving no indication the results came from the United Nations chemical weapons inspectors.
