Sen. Chris Murphy and allies appeared in front of the Capitol on Thursday to push legislation that would hamstring President Donald Trump's ability to unilaterally first-strike North Korea without Congressional authorization. Appearing with Murphy were a gathering of anti-war protestors, including Code Pink activists, and colleagues Sen. Ed Markey, the war hero Sen. Tammy Duckworth, and Rep. Sheila Jackson Lee, a star of Trump-era politics, among others. Co-sponsoring the Senate bill with Murphy is Sen. Cory Booker; both Murphy and Booker are widely believed to have future designs on the White House-- and Sen. Bernie Sanders is on the bill, as well.

The legislation "will make it very clear that, absent an attack or an imminent threat, the president has to come to Congress for prior authorization" to launch a strike on the Kim regime, Murphy told reporters on a call earlier this week. "I think that if we were able to get this very simple resolution on the floor of the Senate, it would pass. … I worry that the president's enthusiasm will not be checked by the advisors around him."
