In recent comments, Trump talks history of U.S. tariffs. Here's a fact check.

President-elect Donald Trump made claims about the history of U.S. tariff collection as he defended his plan to raise tariffs on goods from countries like China and Mexico in a news conference this week, claims historians say are at odds with the facts.

In particular, Trump exaggerated the impact of tariff hikes during his first term, falsely claiming that "no other president took in 10 cents" of revenue from trade collections on Chinese imports. Trump also pointed to 19th-century tariff increases championed by former President William McKinley as evidence that his plan could benefit the economy.

But data shows the federal government had been taking in billions in revenue from tariffs on Chinese imports long before Trump came to office, and historians say the high tariff era of the 1890s was economically rocky for Americans.
