Bernie Sanders rained on Hillary Clinton’s Capitol Hill parade on Tuesday.

Clinton, the frontrunner for the Democratic presidential nomination, was in Washington for a series of friendly talks with lawmakers. After one of those meetings, Sanders, who is challenging Clinton for the nomination, hijacked a set of microphones usually reserved for Senate leaders and questioned Clinton’s bona fides on issues ranging from regulating banks to climate change. As the Hill writes, Sanders is pushing a $15-an-hour federal minimum wage and $1 trillion in infrastructure spending. “I think the secretary has not been quite so clear on those issues,” the Vermont senator told reporters.

Climate control: Clinton actually isn’t afraid to talk about global warming, and wants her fellow Democrats to join her, as National Journal writes.

Several senators said she cautioned that Democrats can’t forget coal country can’t be left behind in the fight against global warming.

Politico writes the Transportation Security Administration has a new strategy for improving its performance in catching airport security threats. A month after the agency was embarrassed by its near-total failure in a covert security audit, Homeland Security Secretary Jeh Johnson has ordered it to pursue an improvement plan that will require more hand-wanding of passengers, more use of bomb-sniffing dogs and more random testing of luggage and travelers for traces of explosives. All that will likely mean longer lines and more spending by the government.
