Hamilton's mayor fires back at Trump over NAFTA tweets

Hamilton Mayor Fred Eisenberger took to Twitter Sunday to call out U.S. President Donald Trump's tweet saying he may have to terminate NAFTA after both Canada and Mexico were "being very difficult."

"The only thing that needs to be terminated is your presidency," Eisenbergerwrote."Save yourself and your country. Resign and you will be popular everywhere."

During a campaign rally on Tuesday, in Phoenix, Ariz., Trump said he didn't think the U.S. could make a deal, and would end up"probably terminating NAFTA at some point, probably."

The U.S. negotiator who worked on the original North American Free Trade Agreement says that despite Trump's suggestions, he will not likely terminate the deal anytime soon.

Ambassador Carla Hillswas George H.W. Bush's trade representative presidingover the initial talks in the early 90's. Shetold CBC News Network'sPower & Politicsshe has been assured by people close to Trumpthat his threat was actually referring to a mechanism that could be enacted five years from now, after an assessment hadbeen made into whether all three parties had met their commitments.

"Let's hope that's what he intended," she told host Rosemary Barton. "It's a better interpretation than an ending of the agreement when our economies are so closely linked and we have so many jobs that are dependent."

Windsor MayorDrew Dilkens similarly responded to trump on Twitter, saying, "35 of 50 States call Canada their # 1 customer. I look forward to hearing the position of elected officials from those states."
