Trump says he wants huge tariffs if elected. That could send inflation spiking.

• Trump has plans for at least a 10% universal tariff on US imports, he told Time Magazine.
• He argues that such a levy wouldn't lead to increased inflation.
• But research from the bipartisan Tax Foundation suggests otherwise, and says Trump's 2018 trade war was also economically damaging.

Former President Donald Trump has made it no secret that he plans to build a wall of tariffs around the US, with higher rates applied to those he sees standing in the way of American trade.
