Some man-on-man action disrupted a Rick Santorum rally at a Christian school in suburban Arlington Heights on Friday.

As Santorum addressed the crowd, two men in the back stood up and started yelling, "Mic Check!" Then, when they had everyone's attention, embraced in a prolonged kiss, FM News 101.1 reported.

The crowd responded by chanting, "USA! USA!," as security escorted the men out of the room.

Patch Local identified the men as Timothy Tross and Ben Clifford. The pair told the Patch that Santorum's stance against gay rights is what prompted their protest kiss.

About 2,000 people attended the Santorum event, while about 50 protested outside, according to the Patch.

Santorum continues to stump in Illinois. On Sunday, he's expected at the Moody Bible Church in Chicago. The Duggar Family, of reality-TV fame, will be there to campaign on his behalf.
