Four more states on Thursday night signed on to join the defense of ObamaCare against a lawsuit seeking to dismantle the health care law. 

Colorado, Iowa, Michigan and Nevada are asking a federal court for permission to join a coalition of 17 states, led by California, that are defending ObamaCare in an ongoing lawsuit filed by Republican attorneys general. 

“The Affordable Care Act provides important protections — including protecting people with pre-existing conditions — care for hundreds of thousands of residents in Michigan,” Michigan Attorney General Dana Nessel said Thursday, according to the Detroit News. 

{mosads}The Democratic states are appealing a Texas judge’s December ruling that ObamaCare is unconstitutional because it can’t stand without the individual mandate penalty, which Congress recently repealed. 

Because the Trump administration declined to defend ObamaCare against the lawsuit, California and its coalition filed to intervene in the case.
