Two fraternities that threatened to defy the University of Virginia's efforts to impose new regulations governing their parties say they will sign the agreement after all.

The university wanted stricter rules on alcohol and security at the parties following a Rolling Stone article that described a culture of campus sexual violence heavily intertwined with fraternity parties. While much of the article has been discredited, U.Va. maintained the suspension of its fraternities and pushed ahead with the new rules.

Kappa Alpha and Alpha Tau Omega had said the agreement was unnecessary and their local chapters wouldn't sign it. On Friday, the fraternities' national organizations said in a statement that the chapters would sign the agreement before Friday night's deadline because the university would otherwise not lift their suspension.
