President Trump told reporters on Air Force One Thursday evening that he wants to send 2,000 to 4,000 National Guard troops to the border with Mexico.
On Wednesday, Trump signed a memorandum to deploy the National Guard, saying "the security of the United States is imperiled by a drastic surge of illegal activity on the southern border," but didn't share any numbers until Thursday. Trump also said his administration is "looking" at how much it will cost to send so many troops to the border, adding, "we'll probably keep them or a large portion of them" until a border wall is built.
