Mexico currently supplies around 70% of the U.S. tomato market, up from 30% two decades ago, according to the Florida Tomato Exchange.

While Mexico was spared from Trump's so-called "Liberation Day" tariff rollout on April 2, the 30% rate for the E.U. is 10 percentage points higher than what the president said he would apply to America's largest trading partner in April but lower than his mid-May threat of 50%.

During an interview with CNN on Sunday, Sen. Alex Padilla (D-CA) spoke about President Trump's tariffs on Mexico.

Mexico's President Claudia Sheinbaum reacted Saturday to a letter from U.S. President Donald Trump announcing new tariffs to be imposed on her country.

President Donald Trump posted letters to the leaders of Mexico and the European Union, saying they had not done enough to head off the new tariffs.
