US President Donald Trump on April 5, 2018 said he would send thousands of National Guard troops to the southern border, amid a widening spat with his Mexican counterpart Enrique Pena Nieto. The anti-immigration president said the National Guard deployment would range from 2,000 to 4,000 troops, and he would 'probably' keep many personnel on the border until his wall is built -- spelling out a lengthy mission. / AFP PHOTO / HERIKA MARTINEZ (Photo credit should read HERIKA MARTINEZ/AFP/Getty Images
