Union Rally Supports Keystone XL Pipeline

Hundreds of union workers rallied in support of a regional pipeline construction project that its members say would create thousands of jobs and improve the local economies of cities alone the line's route.

The rally took place at the Tulsa headquarters of the Pipeliners Local 798. The union claims more than 6,500 members across the country.

The Keystone XL Pipeline would transport oil from tar sands in Canada to refineries along the Texas Gulf Coast.

The project has drawn strong opposition from environmental groups like the Sierra Club, which says if a section were to leak it would threaten the drinking water supply for millions of Americans.
