NOT REAL: Furious Chelsea Clinton Thrown To The Floor And Handcuffed After Senator Lindsay Scandal Linked To Clinton Foundation

An official list of all senators in U.S. history reveals only one with the last name of Lindsay; he represented Kentucky for about two weeks in 1893. Cory Booker and Robert Menendez represent New Jersey in the U.S. Senate. Nevertheless, the story is just one of several involving Clinton that refers to the nonexistent Sen. Lindsay.

Vernal Heights is not one of Florida's more than 200 municipalities. And the photograph of a man identified as the town's police chief comes from a Greek stock photo site.
