Daryl Hannah and Rfk Jr. were arrested in Washington D.C. along with 45 other activists on Wednesday, when the protestors tied themselves to the White House gate in an attempt to prevent the Keystone XL pipeline.

Activist Bill McKibben, civil rights leader Julian Bond and Sierra Club executive director Michael Brune were also among those arrested for protesting the proposed $7 billion pipeline, which would carry oil derived from western Canada to refineries in the Texas Gulf Coast, according to The Daily News.

Daryl Hannah, who starred in the films "Kill Bill" and "Splash" was also arrested in Texas back in October for protesting the pipeline.

"It's incumbent upon us, upon citizens, to show up and stand up and take action," Hannah told Democracy Now. "The polls show that the majority of people in this country are very, very concerned about the climate crisis and want action. And so, the only way that's going to happen is if we insist upon it. President Obama again and again says, 'Push me.' Well, we need to get out there and push him."

President Obama, who called on congress to address the issue of climate change in his State of the Union Address on Tuesday night, has twice rejected the Keystone XL pipeline because of the sensitive land it was originally planned to pass through in Nebraska.

It is unclear how President Obama will proceed now that the governor of Nebraska, Dave Heineman, has approved a new route.

Since the pipeline crosses international borders into Canada, it falls under the State Department's jurisdiction. However, experts expect the president to make the final decision.

In the meantime hopefully Hannah can stay out of jail. At least this time she was arrested with Rfk Jr. , who is a lawyer.

The son of former U.S. Attorney General, Robert F. Kennedy, Rfk Jr. specializes in environmental law.
