Sen. Lisa Murkowski gavelled in the Senate Energy and Natural Resources Committee this morning with a Tsimshian mallet. On her first day as chairman, the committee passed a bill to approve the Keystone XL Pipeline, by a vote of 13 to nine, without amdendments. The bill is the first priority of the new Republican leadership of the Senate. It now heads to the Senate floor and debate scheduled to begin next week. The House is expected to pass its version tomorrow.
