With tears in his eyes, North Korean defector Ji Seong-ho stood up and pumped a pair of crutches proudly in the air as President Donald Trump applauded his bravery and slammed Kim Jong-un's authoritarian regime during his first State of the Union address on Tuesday.

"We are joined by one more witness to the ominous nature of this regime," Trump said as he introduced Seong-ho, who was sitting in first lady Melania Trump's gallery box alongside the parents of Otto Warmbier, the American college student who died after suffering injuries while being detained in North Korea.

To say Ji had a "rough" childhood would be an understatement.
