'Clearly delusional' Trump deluged with ridicule for bizarre claim that his Poland speech was 'best ever'

President Donald Trump boasted that his speech two years ago in Poland was considered one of the best in American history, and left many wondering what he was talking about.

Trump delivered a Stephen Miller-penned 2017 speech ahead of the G20 summit that warned of dire consequences for the West if borders and citizenship weren't clearly defined and restricted, and he bragged Wednesday that it was widely considered among the most well-received by a U.S. president.

"Some people said it was the best speech ever given by a president in Europe," Trump said. "But I did not say that, I'm just quoting"others."

Twitter users tried to make sense of his claim.
