CINCINNATI -- President-elect Donald Trump said he would repeal Obamacare and improve conditions for working class Americans during a "Thank Your" Tour speech in Cincinnati Thursday night.

Trump began his speech by thanking his supporters and touting his campaign as "a grassroots movement the likes of which the world has never seen before."

"You're going to be happy," he said. "We're all going to be happy"

Trump spoke about the reduction of mining and manufacturing jobs, blaming in part the North American Free Trade Agreement. He pledged to "fix " or "terminate" the accord signed with Mexico and Canada during Bill Clinton's presidency.

"The Rust Belt has been hammered, and it's one of the reasons I won," he said. 

Trump also said he would "fix" poor rural communities. He said he planned to stop businesses from moving overseas.

"From now on, it is going to be America first," he said. "We're going to put ourselves first."

Trump also blamed Obamacare for economic problems.

"By the way, we are repealing and replacing Obamacare," he said.

Trump didn't divulge specifics about his economic plan, but said it involved "massively" lowering taxes and loosening business regulations to allow better competition with foreign companies.

"Anything we want for our country is now possible," Trump said.
