Tuesday Video: Why is the White House surrounded by people holding hands?

In case you missed it- the mainstream media tends to overlook such things - an estimated 10,000 to 12,000 protesters converged on the nation’s capitol Sunday to press President Obama to block construction of the 1,700-mile Keystone XL pipeline. The pipeline is designed to  transport tar-sands oil from Canada to refineries on the Gulf of Mexico.

The rally concluded with a human ring encircling the White House. It was a fitting sequel to August’s lengthy protest in which 1,252 protesters were arrested.
