White House Press Secretary Robert Gibbs brushed off accusations by former Alaska Gov. Sarah Palin (R) that incoming chief of staff Pete Rouse had worked against Alaskans and continued to vote in the state despite living in Washington, D.C.

"It's a fairly silly accusation," Gibbs said. "Pretty baseless."

The remark came on the heels of President Obama's announcement Friday that Rouse would replace outgoing chief of staff Rahm Emanuel. 

Palin has also said that Rouse — then Obama's chief-of-staff during his time as senator of Illinois — organized political attacks against her during her time as governor and in the 2008 presidential race.

"Alaska's Pete Rouse (@ least he claims to be "Alaska")finally comes out of the shadows; Obama looks to appt him COS;strange doings in the WH," she tweeted Sept. 22. "(Rahm's the smart one...bailing before Nov) Now, check out possible COS Pete Rouse. His background, voter reg in AK,etc. It's a small world."

She continued a week later as rumors about Rouse replacing Emanuel began to build.

"Alaska media slept on the job for how many years re: Obama senior advisor Pete Rouse's claim to be AK resident and "local" voter? For shame," she said.

When a reporter said Rouse had voted absentee in Alaska in 2008, Gibbs clarified Friday that Rouse is currently registered to vote in D.C.
