Trump's words of encouragement came nearly an hour after Senate Republicans unveiled their so-called skinny repeal bill, which would eliminate ObamaCare's individual mandate permanently and repeal the employer mandate for eight years.

The bill would also end the Affordable Care Act's medical device tax for three years and gives states more leeway to alter their healthcare systems.

The skinny bill is likely Republicans' best chance at keeping their seven-year push to overhaul the country's healthcare system alive, though some GOP senators have already indicated they will not vote for the measure if House Republicans don't guarantee they will work out a more comprehensive healthcare bill in conference.

A Senate vote on the skinny bill is expected after midnight.
