Donald Trump, the presumptive Republican presidential nominee, is casting a wide net during his search for a vice president.

And that net includes a lot of former foes.

According to Ben Carson, who was on Donald Trump's VP selection committee, Florida Sen. Marco Rubio, Ohio Gov. John Kasich, Texas Sen. Ted Cruz and New Jersey Gov. Chris Christie are all on Trump's list of potential VP candidates.

These former candidates are on Trump's list despite how nasty the GOP race got before the other hopefuls dropped out.

One person listed who did not run against Trump is former vice presidential nominee Sarah Palin, though Palin has voiced concerns about running.

"Well, I want to help and not hurt. ... I don't want to be a burden on the ticket, and I realize in many eyes, I would be a burden. I just want the guy to win," Palin said.

As for Carson, he also says he wouldn't be a good fit for the Donald. Carson's business manager told The Washington Post, "He's not interested."

The 2016 GOP convention begins July 18 in Cleveland.
