Gen. Colin Powell is likely to serve a second stint as chairman of the Joint Chiefs of Staff - and won't bump Dan Quayle off the GOP presidential ticket in 1992, a top White House official said Saturday.

White House chief of staff John Sununu firmly rejected suggestions Powell might replace Quayle as Bush's running mate."A Bush-Quayle ticket is a lock-solid ticket in 1992," Sununu said on CNN's "Evans & Novak" program.

"General Powell has indicated to a number of us he'd like to be considered for another stint as chairman of the Joint Chiefs. I think that's the right package," Sununu said.

Asked whether Powell would be reappointed, Sununu said that "discussion hasn't taken place but I can't imagine that that would not happen."
