1. KEYSTONE XL
Facebook founder's immigration advocacy infuriates pipeline opponents
Keystone XL opponents will take a break tomorrow from targeting President Obama to shine a critical spotlight instead on one of his supporters: Facebook founder Mark Zuckerberg. Advocacy group 350.org tomorrow morning will descend on Facebook's Menlo Park, Calif., headquarters to protest a Zuckerberg-backed political action group's funding of television spots that praise senators for backing the pipeline, which would carry oil sands crude from Alberta to Texas.
