Mitt Romney promised to repeal and replace President Obama’s signature health care overhaul on Thursday following the Supreme Court’s decision to uphold the law.

“What the court did not do on its last day in session I will do on my first day if elected president of the United States,” Romney said from Washington, D.C. with the Capitol building as his backdrop. “I will act to repeal Obamacare.”

The presumptive Republican nominee sounded subdued, particularly in comparison to the fiery tone of his last couple speeches leading up to the court’s ruling. He stood behind a podium donning the phrase, “Repeal & Replace Obamacare.”

Calling the law a job-killer, he said it “was bad law yesterday [and] it’s bad law today.”

“This is a time of choice for the American people,” he said. “Our mission is clear: If we want to get rid of Obamacare we’re going to have to replace President Obama.”
