Story highlights Joni Ernst says she hasn't been contacted by the Trump campaign about serving as his running mate

Says she thinks he has someone else in mind for the position

(CNN) Iowa Republican Sen. Joni Ernst is rebuffing the idea that she may be asked to join Donald Trump's presidential campaign as his running mate, saying she hasn't been contacted about joining his ticket.

Ernst, speaking on a conference call Thursday with the Des Moines Register's Jason Nobles and other reporters , added, "If I was being considered, somebody, I think, would have reached out to me. Nobody has reached out."

When asked if she would accept if offered the position by Trump, she said, "I don't think an offer is going to be forthcoming so I really haven't considered that option, to be honest."

"I think his intention is to announce at the convention, and that's coming right up," she added. "I think he must have his eyes set on somebody else, and that's OK."

Ernst is a currently serving her first term in the Senate and would be a relatively inexperienced choice for Trump, who has stressed that he is considering someone with political experience who could help him get his legislative agenda through Congress.
