Senate Democrats today on Capitol Hill refused to attend committee votes on two of President Trump's nominees. They did not boycott the hearing on Alabama Senator Jeff Sessions to be the next Attorney General. Instead, they focused on Trump's dramatic firing yesterday of Acting Attorney General Sally Yates. At the hearing, Illinois Senator Dick Durbin emphasized that, "this is a constitutional moment for us to consider how the next attorney general will deal with the remaining three years and a 11 months of this president." Matt Ford, who covers law and the courts for The Atlantic, has more on Democrats' dramatic showdown.
