TV channel KMGH-TV in Denver, known as 7 News, mistakenly showed a photoshopped cover of Paula Broadwell's biography of David Petraeus with the title "All Up In My Snatch."

The channel's news director said the reporter pulled the image of the book from the Internet and admitted to the mistake calling it "embarrassing."

The original title of the book is "All In: The Education of General David Petraeus,"

"It was a mistake," said KMGH-TV News Director Jeff Harris.

"It was a regrettable and an embarrassing error. We are mortified this appeared during our 5 p.m. news broadcast. The editor pulled the image of the book cover from the Internet without realizing it had been doctored. We sincerely regret the error and have corrected the story to avoid any recurrence of its broadcast. We are following up internally as well to avoid a repeat of this inexcusable oversight," Harris said.

Petraeus resigned as the CIA director last Friday after the affair was uncovered by the FBI. Officials have identified the woman as Broadwell, a 40-year-old married woman with two young children.

The FBI discovered sexually explicit emails on David Petraeus' email account addressed to his mistress Paula Broadwell, including one that talked about "having sex under a desk," according to the Daily Mail.

The sexually explicit emails were discovered by the FBI when it was investigating complaints by Jill Kelley that Broadwell was sending her harrassing emails asking her to back off from Petraeus.

The investigation also has Congress and members of the White House questioning why they were not informed earlier about the whole ordeal and whether national security was compromised.
