A national group has launched a campaign to highlight Senate Majority Leader Mitch McConnell’s environmental record.

The video released today by the Natural Resources Defense Council’s Action Fund highlights the money that “corporate polluters” spent in political contributions to McConnell and other members of Congress. In the first 50 days of McConnell’s leadership, the ad points to McConnell’s support of projects like the Keystone XL pipeline and opposition to federal restrictions of greenhouse gases that contribute to climate change.

Sen. Mitch McConnell was formally sworn in Tuesday as the Senate’s majority leader, and for the first time in eight years Republicans control both houses of Congress.

As expected, U.S. Sen. Mitch McConnell was chosen Thursday by Republican members to be the next Senate majority leader.

The vote was unanimous, according to the senator's office. McConnell officially takes up the post in January.

He becomes only the second Kentucky senator to hold the post. (The first was Democrat Alben Barkley, who was majority leader in the late 1930s and early '40s and later served as vice president under President Truman.)
