Tea Party favorite Dr. Ben Carson said the Obama administration’s healthcare reform law is the worst thing to happen to the United States since slavery.

“I have to tell you Obamacare is, really I think, the worst thing that’s happened in this nation since slavery,” Carson said during a speech at the Values Voter Summit on Friday.

In his fiery speech Carson went on to say that the healthcare law is making all Americans “subservient.”

“And it was never about healthcare, it was about control,” Carson said to applause from the crowd.

In March students at Johns Hopkins University’s medical school launched an effort to replace Carson as their commencement speaker after Carson made comments comparing gay marriage to bestiality and pedophilia.
