Former Republican presidential candidate Carly Fiorina's endorsement of Texas Sen. Ted Cruz Wednesday prompted another unexpected Cruz ally to come out of the woodwork.

Meghan McCain, the daughter of former GOP nominee and Arizona Sen. John McCain, told Fox News hours after Fiorina showed up at a Cruz campaign rally in Miami that she, too, has chosen to support the Texas senator.

"I was a huge, huge Carly Fiorina fan and supporter," McCain told Fox News' Neil Cavuto. "And I think she has the capacity to get a lot of young, conservative women taking a second look at Ted Cruz.

She then added, "For me, honestly, I've been hesitant about Ted Cruz and the Carly Fiorina endorsement has swayed my personal opinion."

Both McCain and Fiorina are steadfast opponents of GOP front-runner Donald Trump, although McCain's father is also a leading critic of Cruz. Earlier this year, the Arizona senator even refused to outright confirm whether he thought Cruz's Canadian birth status disqualifies him from serving as commander-in-chief.

But Fiorina, and now McCain's daughter, appear to believe the first-term senator is eligible and would have no problem defeating Hillary Clinton, the presumptive Democratic presidential nominee, in a general election matchup.

"He has stood up and fought for our right to bear arms. He has fought for our religious liberties," Fiorina said Wednesday. "We need a real conservative … that is the only way we will beat Donald Trump, and that is the only way we will beat Hillary Clinton."

"Ted is the man to do it," she said.
