The nation's largest labor union is poised to back President Barack Obama in his bid for a second term.

The National Education Association represents 3.2 million schoolteachers, administrators and educators. President Dennis Van Roekel (ROH'-kul) says Obama has proven his commitment to funding public education and keeping Social Security and Medicare intact.

The recommendation by the union's political action committee makes it the first major union to signal formal support for Obama's re-election. The union's delegates are expected to vote in favor of the recommendation at a meeting in July. The union also backed Obama in 2008.

Most labor unions are expected to support Obama's re-election bid, though some complain the president hasn't fought hard enough on all their issues.
