Concerning his idea to impose 1000% tariffs on imports in his speech today: 

Coffee is ground in the United States, and the country is the world's largest consumer of coffee/

While the US drinks more coffee than any other country, most of the coffee consumed in the US is imported from countries like Brazil, Colombia, and Switzerland. However, coffee is grown in some limited areas of the US, including Hawaii, Puerto Rico, and California. 

Harris, please make an ad where you show what the cost of coffee will be after his 1000% tax increase? Yes 50$ coffee here we come!
