Henry Kissinger and George Shultz will not endorse Hillary Clinton in the 2016 presidential election, even though the Democratic nominee considers the former to be a close personal friend and mentor.

“We are not making any endorsement in current presidential election. We are dedicated to fostering a bipartisan foreign policy, and we will devote ourselves to this effort now and after the election,” former secretaries of state Kissinger and Shultz said Friday in a joint statement.
