Senate Majority Leader Chuck Schumer’s office was flooded with demonstrators on Monday, as House staffers protested for legislation to combat climate change and demanded that the Democratic leader resume negotiations with Sen. Joe Manchin (D-WV). Capitol Police arrested six of the protesters—there were more than a dozen in total—less than an hour after the demonstration started. As Axios reported, Manchin recently thwarted Democratic ambitions to pass a climate, energy, and tax package, and many of the party’s lawmakers doubt that he and Schumer will ever reach a climate deal. A West Virginia representative, Manchin not only comes from a coal-dependent state, but has much of his personal wealth wrapped up in the industry as well.
