The Senate parliamentarian, Elizabeth MacDonough, has determined some parts of the Republicans’ healthcare bill—including the plan to defund Planned Parenthood for one year—violate a 1985 law known as the Byrd rule, which means these provisions cannot pass the Senate without a full 60 votes. Republicans currently hold 52 seats in the Senate. President Trump is continuing to demand Republicans pass a plan to repeal and replace the Affordable Care Act, despite the fact that Senate Republicans have now failed to pass multiple versions of the bill because of dissent within their own party. Last night, Trump tweeted, “If Republicans don’t Repeal and Replace the disastrous ObamaCare, the repercussions will be far greater than any of them understand!”
