Texas Sen. Ted Cruz has staked his campaign on Indiana -- where polls show him trailing Donald Trump by double digits. And as voters head to the polls Tuesday, Cruz launched into a seven minute rant on Trump, accusing the front-runner of being a "pathological liar," a "narcissist" and "utterly amoral." Cruz's comments came in response to Trump's claims in a TV interview that Cruz's father associated with Lee Harvey Oswald before the assassination of President John F. Kennedy.
