Washington (CNN) – An outspoken liberal advocacy group is using a new television advertisement to take on President Obama over his recent decision to expand the areas available for offshore oil drilling.
Last month, the president announced a new policy that opens up large swaths of U.S. coastal waters in the Atlantic Ocean and the Gulf of Mexico to oil and natural gas drilling. Three weeks later, an offshore oil rig exploded and collapsed, creating a massive oil slick that threatens the Gulf Coast region.
Friday Obama maintained his commitment to the new policy.
"So, let me be clear," the president said, "I continue to believe that domestic oil production is an important part of our overall strategy for energy security, but I've always said it must be done responsibly, for the safety of our workers and our environment."
Now MoveOn, a liberal advocacy group, wants Obama to reinstate the ban on new offshore drilling.
"Sometimes great leaders are tested," the narrator says in MoveOn's new 30-second television ad as images of President Obama in the Gulf Coast region appear on the screen. "For decades, oil companies have dictated our energy policy," the commercial claims. "President Obama, will you lead our country into the clean energy future?," the ad queries.
The ad ends with images of environmental and ecological devastation and of an offshore oil rig set aflame. The commercial implores Obama to reinstate the ban he partially lifted last month.
A MoveOn spokesman tells CNN that the advertisement will run on national cable, including CNN, for one week and will start airing "later this week."
"MoveOn is still working out the exact budget," of the ad buy, the spokesman said.
