U.S. President Donald Trump has urged Republicans in Congress to repeal the Obamacare plan by former president Barrack Obama and work on a healthcare plan that he said would draw Democratic support.

 In a tweet following the loss of support for a Senate Republican bill,

Trump said, "Republicans should just REPEAL failing ObamaCare now & work on a new Healthcare Plan that will start from a clean slate. Dems will join in!"

Democrats have insisted that they will not cooperate with any Republican legislation that repeals President Barack Obama's landmark healthcare law, but would work in a bipartisan way to improve it.
