Trump signed legislation that restricted importation of formula from Canada.
In 2019 Trump signed the United States-Mexico-Canada Agreement – (which replaced the North Atlantic Free Trade Agreement enacted in 1998 by then-President Bill Clinton) – that restricted baby formula's import from our Northern neighbor.
Trump planted the seeds for this with his "rewriting" of NAFTA in 2018. He put a nearly thirty percent tariff on baby formula being imported from Canada. Do you suppose that he got any financial support from Abbott Labs or other corporations who manufacture baby formula?
