President Donald Trump bragged to donors he lied to Canadian PM Justin Trudeau.
Trump refuted his claims about Canada not having a trade deficit with the US.
In a leaked audio, he refused to believe Trudeau's claims--despite not knowing the facts.
"I said, 'Wrong, Justin, you do.' I didn't even know ... I had no idea. I just said, 'You're wrong.'
The Office of the US Trade Representative says the US has a trade surplus with Canada.
