Apparently, in addition to halting trade negotiations with Canada, an additional 10% tariff is to be applied to imports from Canada. It’s unclear which imports will be tariffed (i.e., will USMCA-covered goods be affected?).

To me, it will be interesting to see (1) how much measured policy uncertainty rises, and (2) whether anybody believes in the durability of Trump’s latest trade threat.

Trump: “They cheated on a commercial. Ronald Reagan loved tariffs and they said he didn’t. And I guess it was AI or something. They cheated badly. Canada got caught cheating on a commercial. Can you believe it?”
You know, folks can see and hear the complete speech with their own eyes and ears. Will they deny what they see with their own eyes in fealty to the Dear Leader? It’s just astonishing the extent to which followers will accept the Big Lie.
Do you think Trump really believes it was AI? Is he so senile that he believes everything his handlers tell him? Or is he just a bald faced liar? Or maybe all three.
By the way, the youtube of the speech was posted on the internet decades before the invention of AI. And its not just that speech. Reagan expressed similar sentiments about tariffs in many other recorded speeches.
I wonder which tariff law exemption allows the President to impose a tariff because he is embarrassed by a TV commercial that demonstrates that he is a fool. Trump’s own National Insecurity?
I’d like to see that question raised when the Supreme Court hears the IEEPA case. Seems germaine. It would also be fun to watch the Supremes squirm.
The Ronald Reagan Presidential Foundation & Institute says it is pursuing legal action against Canada for the ad using video footage of Reagan.
They have no grounds to do so. While a presidential library and museum are built with private donated funds, like the Reagan Foundation, they then are turned over to the government which maintains and operates them. All records contained including documents, films, audiotapes and videotapes are property of the US government under the jurisdiction of the National Archives. The Reagan Foundation has no legal claim to them.
Further, the Reagan library uploaded the clip of Reagan’s April 1987 address to YouTube eight years ago and listed its access and use as “unrestricted.”
So the Reagan Foundation is full of it. And they are demeaning the memory of their namesake in obeisance to Donald J. Trump. It says something about the modern Republican Party that they have completely rejected their former paragon. It’s like a regime change in the old Soviet Union in which revered predecessors are erased from history for their “mistakes.”
