Lindsey GrahamLindsey Olin GrahamPence met with silence after mentioning Trump in Munich speech The Memo: Trump and McCabe go to war Graham seeks new Rosenstein testimony after explosive McCabe interview MORE said during the lower-tier Republican presidential debate Thursday that he would do all that is necessary to defeat Islamic militants, including monitoring mosques. 
"The people who are dying for a better America, you better change course. And she doesn't represent the change that we need," Graham (R-S.C.) said of Hillary Clinton, the Democratic front-runner. 
"Do we all agree that ISIL is not the JV team?" Graham said, using an alternate acronym for the Islamic State in Iraq and Syria (ISIS) in reference to President Obama's early remarks describing the group.
"If I have to monitor a mosque I'll monitor a mosque. If I have to take down a cyber wall I'll take it. If I have to send more American troops to protect us here I will do it," Graham said.
His comments came after a Fox News host asked another GOP rival, former New York Gov. George Pataki, how far he would go to root out Islamic extremism, including monitoring a mosque. 
Graham is a long-shot White House hopeful in a field of 17 Republican candidates, but has worked to make national security issues a centerpiece of the 2016 conversation.
The South Carolina lawmaker has repeatedly vowed to send around 10,000 U.S. troops to defeat ISIS in Iraq, as well as pushed for tougher military positions in Syria to defeat the group.
