Past and present sorority members have been flooded with emails expressing concern Congress is going to remove protection for same-sex organizations, such as Greek organizations, on university campuses.

We've received several of these emails from concerned viewers.

"This is an opportunity for us to protect our future," said Executive Director of the National Panhellenic Council Dani Weatherford.

It's a flood of thousands of emails with one common goal.

"We want our members across the country to stay engaged," Weatherford said. "Making sure that young women in the future to choose to join an organization that is women only, if that's something that they're interested in."

She said the letters went out to past and present sorority members in Tennessee because U.S. Sen. Lamar Alexander chairs the committee looking into the Higher Education Act.

The push is to keep language that protects same-sex organizations from any possible university policy in that law.

"What is happening on some college campuses is that the administration is trying to define who can associate with each other," Weatherford said.

She pointed to places like Harvard University, where the administration has already come out against single-sex organizations.

But according to a constitutional law professor we talked with, no one is currently trying to remove that language from the act.

There's also no indication the University of Tennessee is making moves like Harvard.

Lincoln Memorial University law professor Akram Faizer said the first amendment already protects sororities.

"They, like any private citizen, can say what they want, with freedom of association right," Faizer said. "It's called freedom of association. We can associate with those we like. We don't have to be coerced into friendships."
