A spokeswoman for Sandra Bullock says the actress wants her parts of a video promoting Gulf Coast restoration removed until she learns whether oil companies influenced it.
The statement Thursday came after the website DeSmogBlog called the campaign an industry push to get support for drilling and taxpayer money to repair wetland damage caused by the BP oil spill.
Women of the Storm, a New Orleans group that produced the video, lists America's Wetland Foundation as a partner. The foundation lists BP and other oil companies as sponsors on its website.
Anne Milling, founder of Women of the Storm, says the foundation provided experts and information. But she says the video was not funded by oil companies.
