(CNN) – Pete Rouse was just installed as White House chief of staff on Friday, but he's already been facing fire from Sarah Palin for over a week.
Now White House Press Secretary Robert Gibbs is hitting back, calling the former Alaska governor's accusations "fairly silly."
Palin has made clear she's no fan of Rouse - the longtime top Obama aide who has been little seen in the public eye until his elevation to the top White House staff job.
Via several tweets over the last week, Palin highlighted the fact that Rouse - who lived in Alaska during the late 1970s and early 1980s - maintained his voter registration in her state despite not living there for nearly three decades.
"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," Palin tweeted earlier in the week.
Palin may be suggesting that Rouse maintained his voter registration and an address in Alaska so he could be a recipient of the state's yearly permanent fund dividend, which is usually worth at least $1,000. But according to local media reports, Rouse's name does not appear on the Alaska Permanent Fund dividend records.
Gibbs said Friday that Rouse has changed his voter registration to Washington, D.C.
But Palin's anger toward Rouse goes deeper than that, tweeting on September 22: "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."
Palin appears to have been no fan of Rouse for a long time. In her 2009 memoir, she accuses him of being among those in the Obama presidential campaign who allegedly tried to smear her when she was named McCain's vice presidential nominee.
She also accuses him of lifting Obama's "change" slogan from her own gubernatorial campaign in 2006.
"Every part of our campaign shouted 'Change!'" she wrote. "We were amused a couple of years later when Barack Obama, one of whose senior advisers (come to think of it) had roots in Alaska– adopted the same theme," she wrote in reference to Rouse.
