Washington ⢠After Sen. Mike Lee and three fellow GOP senators rebuffed Republican leadersâ plan to vote on a health-care bill, President Donald Trump on Tuesday declared it was time to let âObamacare failâ and force Democrats to the table to work out a solution. Meanwhile, Republican Senate leaders appeared unable to whip enough votes within their caucus to pass their Plan B: repealing Obamacare but delaying its effective date for two years, until after the 2018 midterm elections.
