President Donald Trump signed an executive order Thursday aimed at expanding Americans’ access to health insurance choices, the first official step of his pledge to tackle health-care reform solo after repeated congressional failures to pass legislation repealing Obamacare.

“We’ve been hearing about the disaster of Obamacare for so long,” the president said. “Since I’ve started running and since I became president of the United States, I just keep hearing ‘repeal and replace, repeal and replace.’ We’re starting that process and we’re starting it in a very positive manner.”
