President Donald Trump said he would start negotiations with Canada over a new bridge that connects Michigan and Ontario, threatening to block its opening until the US was given compensation and ownership of half of it.

“I will not allow this bridge to open until the United States is fully compensated for everything we have given them, and also, importantly, Canada treats the United States with the Fairness and Respect that we deserve,” Trump said on social media Monday. “We will start negotiations, IMMEDIATELY. With all that we have given them, we should own, perhaps, at least one half of this asset,” he added.
