Donald Trump on Cruz-Fiorina ticket: ‘What’s he doing picking vice presidents?’

Ted Cruz’s latest play to keep his presidential bid alive has Donald Trump shaking his head.

Fresh off his first traditional policy speech, Trump was back in classic form on the stump in Indiana, making fun of Cruz for tapping Carly Fiorina as his vice president.

“So today I’m in the plane, and I see on television, they have, a new relationship has started: Cruz and Carly,” Trump began, regaling an excited crowd with the latest story in the news cycle. ‘Cruz can’t win. What’s he doing picking vice presidents?”

Knight endorses Trump at Indianapolis rally

Venerated basketball coach Bobby Knight endorsed Donald Trump at a rally in Indianapolis, Indiana on Wednesday, saying that under a Trump administration “…there will never be another thing like what happened in Benghazi.”
Then he alerted the crowd to a new record: Cruz is the “first presidential candidate in the history of this country who’s mathematically eliminated from being president who chose a vice presidential candidate. Okay? It’s a record.”

But Trump quelled the crowds concerns by assuring them that despite wishing Cruz well, “They’re not gonna do it for you.”

On this same evening, Trump received the endorsement of legendary basketball coach Bobby Knight - but that wasn’t the only endorsement he was touting. “All the tough guys endorsed me,” Trump said, noting that he’s also been endorsed by ex-boxer and convicted rapist Mike Tyson. “I like that.”

Tyson was convicted of the sexual assault of a Miss Black America contestant in Indianapolis, Indiana, in 1991, and served jail time in the state.
