Trump false reply to question about keeping jobs in US: "I was honored as the man of the year. Maybe 20 years ago. The fake news heard about it and said, it never happened…"
Either he fell asleep watching the movie below and confused it with his own reality, was inspired by it with his tactics to win elections, or Robin Williams is a time traveller.
“Man of the Year”, 2006, starring Robin Williams.
A comedian who hosts a news satire program decides to run for president, and a computerized voting machine malfunction gets him elected.
I think a funnier premise would be a reality TV star who gets hired for a mockumentary about a reality TV star running for President, except it's not a mockumentary and they don't tell him he actually ran for President until after he wins the election. Except it's not very funny because it's possible that's what actually happened in 2016.
