Former President Donald Trump said he has already decided on who he is choosing as his running mate should he win the Republican Party’s presidential nomination. The GOP presidential candidate shared this with Fox News hosts Martha MacCallum and Bret Baier at a town hall event in Iowa on Wednesday.

However, he maintained an air of mystery around his selection, saying, “I can’t tell you that really, I mean, I know who it’s going to be.”

Elsewhere in the interview, he was also asked about his plans to mend any form of friction between him and any of his former rivals in the GOP presidential race. According to Trump, he is open to resolving their issues. He even mentioned former New Jersey Gov, Chris Christie, who dropped out of the race this week, saying that he has already begun to like him more.

He, however, does not like him enough to make him his vice presidential pick. When MacCallum brought up the idea, the GOP front runner said, “I don’t see it, I don’t see it. That would be an upset. Christie for vice president. Ladies and Gentlemen, I’d like to announce, nah.”

Before Trump’s confirmation that he has a VP pick in mind already, speculations have been flying around as to who could be his potential running mate. Among the names that have been floated for the position are former South Carolina Gov. Nikki Haley and biotech entrepreneur Vivek Ramaswamy, who are both his rivals on the GOP primary front.

So far, Haley has not directly indicated an interest in being Trump’s VP pick. However, she has been accused by Florida Gov. Ron DeSantis of trying to leave the door open for a consideration from Trump. Former New Jersey Gov, who just gave up his presidential bid also alleged that the U.N. ambassador was not taking a very firm stance against Trump because she was nursing hopes of running alongside him should he end up winning the party’s presidential ticket.

In two separate interviews in one weekend, Christie came all out for Haley asserting that her claims that Trump is fit to lead is proof that she is not a serious contender against the former president.
