Washington, September 9 (RHC)-- Democratic presidential pre-candidate Hillary Clinton will deliver a major address on the Iran nuclear deal, voicing support for the agreement, after helping to lay the groundwork for it as secretary of state.

But Clinton is also expected to take a more militant stance on Iran than Barack Obama, vowing to take military action if Iran moves toward nuclear bomb-making capabilities. Obama has only said he would keep military action on the table.

Meanwhile, Hillary Clinton has apologized for relying exclusively on a private email server while she was secretary of state. A day after she told the Associated Press she didn’t need to apologize because "What I did was allowed," Clinton apologized in an interview with ABC News.
