Former Secretary Of State Colin Powell delivered some harsh words for the GOP as a whole on Sunday.

In an appearance on NBC's "Meet The Press," Powell noted that there is a "dark vein of intolerance in some parts of the party."

"What do I mean by that?," he explained. "What I mean by that is they still sort of look down on minorities."

Powell specifically pointed to October 2012 comments by former Alaska Gov. and Vice Presidential nominee Sarah Palin on the attacks in Benghazi, Libya.

"When I see a former governor say that the president is 'shuckin' and jivin' -- that's a racial-era slave term," Powell said, referring to Palin's words on Obama's response.

Powell added that Republicans had become too preoccupied with the candidate-selection process, losing sight of the group's overall message.

"You've got to think first about what's the party actually going to represent," Powell said. "If it's just going to represent the far right wing of the political spectrum, I think the party is in difficulty. I'm a moderate, but I'm still a Republican."

Powell was the first African American to fill the role of Secretary Of State, serving under President George W. Bush from 2001-05. Despite maintaining his allegiance to the Republican Party, Powell has been an ardent supporter for President Barack Obama, giving him a 2008 vote and a 2012 endorsement.
