President Donald Trump intensified his criticism of Canada on Sunday, accusing the country of "ripping" the U.S. off "for decades" as he defended his tariff policies and urged Canadian companies to move their operations south of the border.

In back-to-back Truth Social posts Sunday afternoon, Trump first credited tariffs with strengthening the U.S. auto industry and keeping American manufacturing plants open.

"When I announced that I was running in the 2024 Presidential Election, right at the beginning, Ford was getting ready to close their Big Factory, in Detroit," Trump wrote.
