Trump's visit to Kim was the first time that a seated US president was gaining a foothold in North Korea. However, only agreement was reached between the two nations to resume talks on North Korea's nuclear ambitions. Schumer questioned how little Trump had received for a visit he viewed as a concession.
"He admires these strong men," Schumer told CNN's Anderson Cooper on Tuesday about Anderson Cooper 360. "He has no principles about what rule of law is, what a democracy is, you know, Anderson, this was one of the worst days in American foreign policy, in American diplomatic history for a long time."
] Schumer called the meeting an extension of Trump's "unpredictable" foreign policy that "hurt us in the long run".
"The dictators praise, confuse foreign policy from left and right, what he did in North Korea, to give Kim Jong Un what he wanted, to call him a friend, to pat on his back and nothing to do get absolutely nothing. " he said.
Trump's meeting with Kim was the third time the two leaders met. This time, after a handshake on the North Korean border, they spoke for nearly an hour at Freedom House in the demilitarized zone.
"Would you like me to go over there?" Trump Kim asked as they shook hands. "I agree with that."
Trump and Kim shook hands and patted each other's backs while on North Korean territory before returning south across the border.
Trump later said he was "proud to cross the line" while thanking Kim for the meeting. "I never expected to see you there," Kim Trump said through an interpreter.
"It's reality show foreign policy," added Schumer on Monday. He wants the photo opportunity, he wants the little hit, he has no strategy, knows in the long run where to go, what to do, if anyone thinks that will not hurt America in the short term, they are mistaken. "
