CALGARY, Alberta, Dec. 30 (UPI) -- U.S. billionaire Donald Trump is advocating the controversial pipeline from Canada to the United States, calling U.S. policy "dumb."
The Keystone XL pipeline project would transport oil and gas from Alberta's oil sands to southern U.S. refineries but has brought environmental concerns, prompting President Barack Obama to defer a decision until 2013, the Calgary Sun reported.
