Trump: “You know who else didn't help us?"

President Trump: “You know who else didn't help us? South Korea didn't help us. We have 45K soldiers in South Korea to protect [them] from Kim Jong Un, who I get along with very well. He said very nice things about me. He used to call Joe Biden a ‘mentally retarded person.’” “Joe Biden, he said he’s a mentally retarded person. He was so nasty to Joe Biden. It was terrible.”
