President Trump and his White House counsel plan to visit McAllen, Texas, today amid speculation he may declare a national emergency and try to use Pentagon funds to pay for part of an expanded border wall. Meanwhile, the president’s oldest son, Donald Trump Jr., shared a post on Instagram comparing immigrants to animals. Donald Trump Jr. wrote, “Do you know why you can enjoy a day at the zoo? Because walls work.” Don Jr.'s post echoes President Trump's past comment calling immigrant gang members “animals” and “not people.”
