US Rep. Ron Paul drew cheers from the audience and rebukes from some fellow candidates as the libertarian-leaning Texan called for cutting military spending during tonight's CNN debate.
Paul refused to accept that such cuts might impact national security.
"To cut military spending is a wise thing to do. We would be safer if we weren't in so many places...We have an empire. We can't afford it," Paul said.
Rick Santorum disagreed.
"I would absolutely not cut one penny out of military spending...The only thing that the federal government can do that no other level of government can do is protect us," Santorum said.
As the debate shifted to whether to cut foreign aid spending, Paul again used the opportunity to push for defense spending cuts.
"We have more weapons than all the other countries put together essentially and we want to spend more and more and you can't cut a penny?" Paul said.
Paul also advocated for cutting foreign aid spending, which prompted moderator Anderson Cooper to ask if Paul would cut funding to Israel.
"That foreign aid makes Israel dependent on us...They should have their sovereignty back," Paul said.
US Rep. Michelle Bachmann of Minnesota disagreed with Paul.
"We should not be cutting foreign aid to Israel," Bachmann said. "Israel is our greatest ally."
