Mexican President Andrés Manuel López Obrador hit back at President Trump in a public letter, decrying his plan to impose a 5 percent tariff on Mexican imports because of the administration’s border migrant crisis. “With all due respect, although you have the right to express it, ‘America First’ is a fallacy because until the end of times, even beyond national borders, justice and universal fraternity will prevail,” López Obrador wrote in a letter released late Thursday. The Mexican president said his foreign minister would be in Washington, D.C., on Friday to negotiate with U.S. officials. On Thursday, Trump tweeted that on June 10 the U.S. “will impose a 5% Tariff on all goods coming into our Country from Mexico, until such time as illegal migrants coming through Mexico, and into our Country, STOP.” “The Tariff will gradually increase until the Illegal Immigration problem is remedied,” the president added. White House Chief of Staff Mick Mulvaney told reporters that the tariffs would be raised to 10 percent in July, 15 percent in August, 20 percent in September, and 25 percent in October.
