Susan Rice’s path to becoming U.S. Secretary of State may have hit a roadblock after it was revealed she owns significant stock in Calgary-based energy giant Trans Canada.

The state department is still deciding on the company’s plan to build the $7 billion  Keystone XL pipeline which would cross an international border.

Rice, who’s been tapped to replace Hilary Clinton, could have a conflict of interest.

Rice, who’s married to a Canadian, has investments in several Canadian oil companies that could stand to gain from the pipeline.

The National Resources Defence Council tells The Globe and Mail, Rice will likely either have to step aside, or remove herself from the investments.
