A bevy of Republican presidential candidates is heading to Utah for Mitt Romney's fourth E2 Summit, a gathering of political leaders, business executives and major campaign donors.
Romney's team sent out invitations Thursday for the three-day Deer Valley event that begins on June 11.
Among the confirmed attendees are five potential presidential contenders: Florida Sen. Marco Rubio, Wisconsin Gov. Scott Walker, New Jersey Gov. Chris Christie, Ohio Gov. John Kasich and South Carolina Sen. Lindsey Graham.
A staffer for the summit says former Florida Gov. Jeb Bush was invited, but couldn't make it because of an earlier scheduled trip to Germany, Poland and Estonia.
