Actress Jenifer Lewis rants about Rosa Parks, Emmett Till at rally for Val Demings

"Black-ish" actress Jenifer Lewis called Sen. Marco Rubio, R-Fla., a liar and went off on a bizarre rant about Rosa Parks and Emmett Till at a rally for Democratic Senate nominee Rep. Val Demings, D-Fla., on Tuesday.

"This speech is going to go around the world," a jubilant Lewis exclaimed at Florida Memorial University in Miami Gardens before denouncing Rubio as a "lie" and accusing him of being willing to "cheat and steal."  

"Val Demings is the truth 'cause she knows what a lie is. She also knows, like me, you cannot lie your way to greatness," Lewis told the crowd. "Marco Rubio is a lie. He is – did y'all see that debate? Lied his a-- off." 

It is unclear what alleged "lie" Lewis was referring to or what she meant by "cheat and steal."
