Civil disobedience actions continue outside the White House against the proposed Keystone XL pipeline that would carry oil from Canada’s tar sands to Gulf Coast refineries. A number of protesters were arrested on Tuesday, including the actor Daryl Hannah and Greenpeace USA Executive Director Phil Radford. Among the others to be arrested this week is Elijah Zarlin, who worked as a senior writer for President Obama’s election campaign in 2008. Overall, the group Tar Sands Action says 595 people have been arrested since the protests began earlier this month. The protesters are urging President Obama to veto the pipeline. On Tuesday, White House Press Secretary Jay Carney said he and President Obama have not discussed the issue.
