“Ted Cruz is a desperate candidate trying to save his failing campaign,” Trump said in a statement released by his campaign Tuesday. “It is no surprise he has resorted to his usual tactics of over-the-top rhetoric that nobody believes.”

Trump was referring to Cruz’s remarks earlier Tuesday that Trump is a “pathological liar,” “utterly amoral” and that he “has a real problem with women.”
 
The Texas senator was responding to Trump’s suggestion that Cruz's father might have had something to do with the assassination of President John F. Kennedy.
 
“Over the last week, I have watched Lyin’ Ted become more and more unhinged as he is unable to react under the pressure and stress of losing, in all cases by landslides, the last six primary elections — in fact, coming in last place in all but one of them,” Trump added. 
 
“Today’s ridiculous outburst only proves what I have been saying for a long time, that Ted Cruz does not have the temperament to be President of the United States.”
 
Cruz's campaign earlier in the day used a similar line of attack, describing Trump as "detached from reality" after the businessman invoked a tabloid story in an attempt to link Cruz's father to the man behind JFK's assassination. 
 
Trump surfaced the story, which Cruz's campaign has described as total "garbage," on the day of the Indiana primary, where polls show the businessman could be headed toward a major win.
