President Barack Obama and Labor Secretary Tom Perez will speak to organized labor at the AFL-CIO’s convention next month, said AFL-CIO President Richard Trumka.

Mr. Trumka, who talked with reporters over breakfast Thursday at Washington’s St. Regis hotel — an annual event sponsored by the Christian Science Monitor – said Sen. Elizabeth Warren will also address the labor federation’s convention, which kicks off Sept. 8 in Los Angeles.
