“I feel terrible for the American people because it’s not the American people, and it’s not even elected officials, it’s one person,”

Americans elected Trump, and Americans are failing to do anything to reign Trump in.
These are the official policies for the COUNTRY! So unfortunately, this is not just one person, it is de facto USA as a whole.

If it was only Trump, it would just be Trump refusing to buy Canadian for himself. As it is, the whole apparatus is enforcing these decisions, and they impact all of USA.
