'This is a Religious War.'

Now more than ever it appears the United States must do more to promote religious freedom abroad. What's one way America can encourage rogue nations that oppress Christians and other religious minorities? Money!

South Carolina Sen. Lindsey Graham led a Senate Appropriations Subcommittee to look at how the United States can use the power of foreign aid to encourage regimes to chose religious liberty over religious persecution. Research shows countries that allow religious freedom prosper economically.

"This is a religious war and we must take sides," Graham said, referring to the crucifixions and beheadings of Christians and other religious minorities at the hands of ISIS and other terror groups in the name of Islam.

Oklahoma Sen. James Lankford sits on Graham's subcommittee and stepped out of the meeting to talk to Beltway Buzz about what he hopes the United States can achieve.
