Missouri Senator Claire McCaskill is bucking most of her party in calling for quick approval of a new oil pipeline from Canada.
The Democrat sent a letter Tuesday to Secretary of State Hillary Clinton, urging the Secretary to approve the Keystone XL project. Clinton's approval is needed because the pipeline crosses international borders.
In a phone call with reporters Wednesday, McCaskill said she believes that the company behind the pipeline, Trans-Canada, has made changes to satisfy the concerns of environmentalists in Nebraska.
