Donald Trump read “The Snake” — as he often did during the GOP primary — to his supporters at his afternoon campaign rally in southwest Florida on Monday following terrorist attacks in New York City, New Jersey, and Minnesota over the weekend.

Trump has used “The Snake” in the past to demonstrate his immigration belief that the U.S. should be smart and careful about who is allowed to enter the country.

“The Snake” became a top trending topic on Twitter after the Republican nominee’s rally.
