Mick Mulvaney pointed to photographs of a chain-link fence and referred to it as the old US border wall

Washington (CNN) The White House says it's going to build a wall along the US-Mexico border with new funding appropriated by Congress.

Former Presidents George W. Bush and Barack Obama are the ones responsible for improving border security in places like Sunland Park, New Mexico. In fact, the project to improve the fence in Sunland Park began in summer 2016, prior to President Donald Trump taking office.
