[...] The former president told Varney that the U.S. is sitting on top of what he calls "liquid gold" and that makes the country "more than competitive" because China "doesn’t have that; they have to go and buy everything." Trump stressed that the U.S. has so many natural resources "under our feet," but the radical left, which he referred to as the "crazies," make it very difficult to access and use.
