After massive California oil spill, some residents question if agencies acted quickly enough

Crews on and offshore continue working along Huntington Beach after an offshore rig has leaked at least 144,000 gallons of oil in the Pacific Ocean. It is considered the largest oil spills the area has ever seen.

Martyn Willsher, CEO of Amplify Energy, which operates the pipeline, said Monday there's a possibility a ship's anchor may have ruptured the line.

"We have examined more than 8,000 feet of pipe and we have isolated one specific area of significant interest," Willsher said in a press conference.
