Washington, D.C. ? Tens of thousands of Americans could see more opportunities to mentor children, help rebuild homes and participate in other national service under a measure passed by the House on Wednesday.

The House voted 321-105 to expand AmeriCorps and other national service programs by 175,000 participants. It would also create new groups to help poor communities with education, clean energy, health and services for veterans.

Supporters say the effort comes at a time when more people are interested in serving their communities and more people could use the extra help.

The bill “reaches out to all Americans from all walks of life and asks them to commit to service,” said Jared Polis, D-Colo. “During these difficult times, our nation needs the help of each and every one of us more than ever.”

A Senate committee approved an expansion Wednesday that was somewhat similar, adding 175,000 positions to the AmeriCorps alone. That bill, which triples the size of the program, could reach the Senate floor next week.

President Barack Obama said he was pleased by the House’s action and was eager for the Senate to pass the bill so he can sign it.
