Waiting to be interviewed by affiliate KXTV Wednesday morning, Fiorina is clearly heard taking a dig at her rival for the California Senate seat, Sen. Barbara Boxer, D-California.
"God, what is that hair?" a laughing Fiorina said, while quoting a friend who had recently seen Boxer on television. "So yesterday."
Fiorina also questioned why Republican gubernatorial candidate Meg Whitman had decided to go on Sean Hannity's show the day after winning her party's primary.
"It's really surprising that on the first day of the general [election], Meg Whitman is going on Sean Hannity," she said. "I think it's bizarre…I think it's a very bad choice actually. You know how he is."
Contacted by CNN about the comments, a spokesperson for Fiorina downplayed the remarks. "This was nothing but early morning small talk," Fiorina campaign press secretary Amy Thoma said in an e-mail to CNN.
