From a June 9 post on CNN.com's Political Ticker blog:

Newly-minted U.S. Senate Republican nominee Carly Fiorina added her name Wednesday to the annals of unfortunate politicians caught by an open mic.

[...]

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. [emphasis added]

Hannity hosted Fiorina on his Fox News program in March.
