Donald Trump is urging his supporters to vote on Election Day — but he got one key fact wrong.

In the opening moments of a rally Tuesday night in Palm Beach City, Florida, Trump told the crowd to "make sure you get out and vote, Nov. 28."

The problem with that advice? Election Day is actually Nov. 8.

Trump: Vote on November 28th

Later in the rally, Trump correctly listed the date.

Twitter users quickly latched on to the mistake.
