TransCanada launches two challenges as it argues president violated Nafta, saying it is seeking to recover $15bn spent in push for pipeline's approval
The company behind the rejected Keystone XL pipeline fired off two legal challenges on Wednesday, accusing Barack Obama of overstepping his authority and violating the North American Free Trade Agreement (Nafta).
TransCanada Corporation said it was looking to recover an estimated $15bn it spent over many years trying to win approval for the pipeline before Obama rejected the project last November.
