President Trump on Monday will make a statement regarding healthcare. It will come following a warning to members of his own party via Twitter. Trump tweeted that if Republicans don't repeal and replace Obamacare, "the repercussions will be far greater than any of them understand!" The Senate GOP plan to repeal and replace the Obama-era healthcare law stalled when a group of Republican senators pledged to oppose it. The White House says Trump will be meeting today with "victims of Obamacare" before delivering his statement.
