Palin also couldn't resist tweaking the Obama camp a bit over the Democratic nominee's choice of vice president.
Palin told Gibson that she thinks Sen. Barack Obama, D-Ill., regrets not picking Sen. Hillary Clinton, D-N.Y., as his vice presidential running mate.
"I think he's regretting not picking her now, I do. What, what determination, and grit, and even grace through some tough shots that were fired her way -- she handled those well," she said.
Palin took the mantle of the campaign's only female contender after Obama defeated Clinton for their party's nomination, and picked Sen. Joe Biden, D-Del., as his Democratic running mate over Clinton and others.
Palin has praised Clinton on the campaign trail, and when she was first introduced as McCain's running mate last month in Ohio.
"The women of America aren't finished yet, and we can shatter that glass ceiling once and for all," Palin said as she accepted McCain's invitation to join the 2008 Republican ticket, referring to a line made famous in Clinton's concession to Obama.
Clinton has been reluctant to criticize Palin on the campaign trail so far, but the Obama campaign issued a strong response after ABC News aired Palin's comments.
"Sarah Palin should spare us the phony sentiment and respect. Gov. Palin accused Sen. Clinton of whining, and John McCain laughed when a questioner referred to her by using a demeaning expletive. John McCain and Sarah Palin represent no meaningful change, just the same failed policies and same divisive, demeaning politics that has devastated the middle class," said Obama supporter Rep. Debbie Wasserman Schultz, D-Fla.
The 'Bridge to Nowhere' is not the only controversy surrounding the 44-year-old governor.
Palin is under investigation by the state legislature into whether she inappropriately dismissed Walter Monegan, a member of the Alaska Public Safety Commission, after he refused to fire her ex-brother-in-law, a state trooper.
On Friday the committee investigating "Troopergate" subpoened 13 witnesses including Todd Palin, the governor's husband.
Palin painted her sister's ex-husband Mike Wooten as a dangerous member of the state police who threatened the governor and her family.
"The trooper in question here did conduct dangerous and illegal activities and our personal security detail, when I was first elected, had asked us very appropriately: 'Are there any threats against you and your family?' And I said, well, you know, ironically, yeah, it's a state trooper who's threatened to kill my dad and bring down me and once I got elected. His threats were [that] he was going to bring down the governor and the governor's family, so it was very appropriate that we brought the concerns to the personal security detail. They asked us to bring it to the commissioner, which I did."
Palin said that she believe the state's Personel Board and not the state senate should investigate the case and denied that she appointed the board's members.
Palin, just two years into her first term as governor, made a name for herself as a "reformer" and in her second interview with Gibson on Thursday trumpeted her record of taking on oil companies and corruption in Alaska.
In Thursday's first interview, Palin hewed closely to the McCain talking points, mirroring the presidential nominee's positions on foreign policy and national security.
