WASHINGTON (AP) — The House has approved legislation that would give subpoena power to the presidential commission investigating the BP oil spill in the Gulf of Mexico.

Rep. Lois Capps, a California Democrat, said that Americans want answers from those responsible for the spill, and subpoena power will ensure "no stone goes unturned."

The vote Wednesday was 420-1, with Republican Rep. Ron Paul of Texas casting the only no vote.

President Barack Obama has appointed the seven-member commission to investigate the spill.
