WASHINGTON (AP) – The Latest on Campaign 2016 ahead of the Republican and Democratic presidential nominating conventions (all times EDT):

10:15 a.m.

Bernie Sanders is poised to offer his long-awaited endorsement of Democratic rival Hillary Clinton, hoping to transfer the energy of his supporters into the party’s fight against Republican Donald Trump.

The Vermont senator is joining Clinton at a campaign event Tuesday in Portsmouth, New Hampshire.

The endorsement is the culmination of weeks of negotiations between the Clinton and Sanders campaigns since the final primaries in June.

Sanders has pressed for Clinton’s support of policy stances on higher education, health care and a $15-an-hour minimum wage.

Sanders beat Clinton in New Hampshire by a dominant 22-point margin last February. Many of his supporters have shifted to Clinton but the senator hopes to rally them as a way of preventing Trump from reaching the White House.
