GOP Lawmakers Urging Obama To Take Action in Syria

Remain hesitant to send troops

Congressional Republicans said Sunday that President Obama must stick with his vow to take action should Syria cross a "red line" by using chemical weapons on citizens, amid such mounting evidence, but cautioned against sending in troops.

"The president has laid down the line, and it can't be a dotted line," House Intelligence Committee Chairman Rep. Mike Rogers, R-Mich., told ABC's "This Week." "It can't be anything other than a red line."
