Former prime ministers are encouraging Canadians to fly the flag Saturday as a visible retort against Trump's tariff threats.

Rep. Claudia Tenney (R-N.Y.) announced Friday a proposed bill, the Establishment Act, which seeks to make President Trump’s birthday and Flag Day a federal holiday in the United States.

The flag presented during the performance of the national anthem at Super Bowl LIX was handmade by a Utah-based flag company.
