Flores said no offers have been made at this time.
Cruz acknowledged to reporters Monday that his campaign is in the process of vetting a short list of potential vice presidential picks but would not confirm if Fiorina was on that list.
"We have acknowledged some time ago that we have begun a vice presidential search process," Cruz said. "Any responsible candidate just a couple of months out from the convention would begin that process. We’ve begun examining both a long list and now a shorter list. And that naturally includes a vetting process. At this point, no decisions have been made in terms of who a nominee would be, or what the timing would be of the announcement."
