On 23rd April, US President Donald Trump announced that he has ordered the Department of Homeland Security to block “large Caravans” of migrants from entering the US through the border with Mexico. Despite these orders, around 100 migrants arrived at the US-mexico border today. They have infuriated President Trump triggering a series of angry tweets. In recent weeks, Trump has railed repeatedly about a group of about 1,500 migrants that made a 2,000-mile trek to reach the Mexican border city of Tijuana.
