President Donald Trump tweeted his eagerness Monday to work with Democratic lawmakers to pass a replacement for the Affordable Care Act, which was struck down by a federal judge Friday evening in Texas.

The DEDUCTIBLE which comes with ObamaCare is so high that it is practically not even useable! Hurts families badly. We have a chance, working with the Democrats, to deliver great HealthCare! A confirming Supreme Court Decision will lead to GREAT HealthCare results for Americans! — Donald J. Trump (@realDonaldTrump) December 17, 2018

Trump’s tweet urged the U.S. Supreme Court to confirm the Texas decision, which concurred with a lawsuit brought by 20 U.S. states alleging the healthcare framework is unconstitutional. The ruling by Judge Reed O’Connor is especially peculiar because the healthcare law was upheld by the Supreme Court in 2012 by five current justices who continue to sit on the bench.

O’Connor argued that the Supreme Court ruling was invalidated by the removal by Congress and the Trump administration of the law’s signature individual mandate. The Supreme Court said the individual mandate was constitutional because of Congress’s ability to levy taxes.

Trump celebrated the decision Friday in a series of spirited tweets. The president has long been stung by his 2017 effort to repeal and replace the signature healthcare law of his predecessor, which was sunk with a single “no” vote by former Republican Sen. John McCain of Arizona.

As I predicted all along, Obamacare has been struck down as an UNCONSTITUTIONAL disaster! Now Congress must pass a STRONG law that provides GREAT healthcare and protects pre-existing conditions. Mitch and Nancy, get it done! — Donald J. Trump (@realDonaldTrump) December 15, 2018
