At the end of May, President Donald Trump announced he would enact substantial tariffs against the United States' largest trading partner, Mexico, if they did not take steps to stop migrants from reaching the United States' southern border. The initial threat drew backlash from both sides of the border.

But nine days later Trump declared victory and announced via Twitter a deal was made and the heavily criticized tariffs canceled. But Mexican officials refuted Trump's claim stating the agreement he said his tariffs threat spawned had actually been proposed months prior.
