Hillary Clinton, the presumptive Democratic nominee for president, will speak to a meeting of the American Federation of Teachers (AFT) at the Minneapolis Convention Center on July 18.

Clinton will speak to the 3,000 delegates of the nation's second-largest teachers union.

The union, which has 1.6 million members nationwide, was the first national union to endorse Clinton during her Democratic primary battle with Sen. Bernie Sanders of Vermont. AFT President Randi Weingarten, a Clinton ally and powerful labor leader, will give her keynote address on the same day.

The Clinton speech will come on the first day of the Republican National Convention in Cleveland, during which Donald Trump is expected to become the GOP nominee.

Clinton's alliances with teachers unions go back decades.
