U.S. Capitol Police arrested 138 protesters at two different House office buildings on Monday and charged them with “crowding, obstructing or incommoding” under the D.C. Code. The protesters were all members of the Sunrise Movement, a group of mainly young people fighting for comprehensive climate change policy, who are advocating for a Green New Deal.

Activists were arrested outside the offices of Democratic House leadership—California Representative and Speaker-designate Nancy Pelosi and Democratic Whip Steny Hoyer, who represents Maryland’s fifth district (you can see video from the organization’s action here). Crowds reportedly swelled as large as 1,000 activists, but not everyone put themselves in a position to be arrested.

The Green New Deal was proposed by New York Democratic Representative-elect Alexandria Ocasio-Cortez. It calls for the formation of a bipartisan committee that will aggressively address climate issues to reach ambitious goals, like transitioning the United States to 100 percent renewable energy. Many Democrats have so far wavered in their commitment to the creation of a select committee that would hammer out the details of the legislation.

“The reason we’re planning this [action] right now is the Congress sets the agenda for 2019 before they go home for holiday recess,” Stephen O’Hanlon, the interim communications director for the Sunrise Movement, told Earther, a Gizmodo publication. “We have a handful of days to get the select committee on a Green New Deal on the agenda for 2019. We’ve been growing momentum for weeks.”

Representative Jim McGovern of Massachusetts’ second district spoke with protesters and committed to backing the Green New deal on Monday. After the demonstration, Pelosi pledged to meet with Sunrise activists, according to Vice.
