Former Pennsylvania Sen. Rick Santorum (R) is not too pleased that children will have to get parental permission to attend his speech at a Michigan high school this month.

The Grosse Pointe South High School had originally canceled Santorum’s speech after the student group Young Americans for Freedom raised $18,000 to pay him to speak. The administrators on Wednesday uncanceled the speech, but said students would need to have their parents sign a permission form if they wished to attend.

“That’s disappointing,” Santorum said on Fox News. “That someone who served two terms in the Senate, two terms in the House, ran for president and by all admissions came in second place in the Republican primary, almost won the state of Michigan, actually tied in the number of delegates, campaigned extensively in that state — to have someone like that come and speak at your school, that you’d need a permission slip from you parent as if there is something that person could do to harm your child.”

The speech was apparently canceled because of Santorum’s outspoken opposition to same sex marriage.
