TransCanada says to keep pushing Keystone; investors skeptical

TransCanada Corp said on Friday it will keep pressing to build the Keystone XL oil pipeline from Canada to the United States despite the Obama administration's rejection, but investors were skeptical and suggested it focus on a controversial all-Canadian alternative. TransCanada is also developing the Energy East pipeline, designed to move western oil sands crude to Canada's East Coast, although it too faces opposition from environmentalists who want to stop the industry's expansion.
