The future of Obamacare could be at stake on Tuesday when a group of Democratic-led states and the House of Representatives urge a federal appeals court to overturn a Texas judge's ruling that the U.S. health care reform law is unconstitutional.
Republicans have repeatedly tried to repeal Obamacare, formally named the Affordable Care Act, since its 2010 passage. The Justice Department would normally defend a federal law, but the Trump administration has declined to take that position against a challenge by 18 Republican-led states.
A coalition of Democratic state attorneys general led by California Attorney General Xavier Becerra stepped into the void to defend the law, also called the ACA. The House intervened after Democrats won control in November's elections after many focused their campaigns on defending Obamacare.
