(Updated after the jump with GOP official saying Palin expected to attend dinner)
WASHINGTON (CNN) - Even though Sarah Palin's trip to the East Coast was intended to be low-key and out of the glare of the national media, the Alaska governor has found herself in the political hot seat once again.
With Palin in Washington on Monday attending to state business, Republicans on Capitol Hill are left wondering if she will make an appearance at a major fundraising dinner on Monday night after a late attempt to have her speak at the event fell through.
Although the governor still has a standing invitation to attend as a guest, Republicans don't have a clue if Palin will show up, with just hours left until the event is set to begin.
Sen. John Cornyn, the chairman of the National Republican Senatorial Committee, has personally reached out to Palin to offer her a seat at his table tonight, according to an aide. But as of this afternoon, he has not heard back.
Palin's camp is also remaining mum on her plans, saying there's no word yet on whether she will attend.
A GOP official involved in the planning of the event downplayed the situation as just "a minor distraction" from what is expected to be a successful fundraiser.
Former House Speaker Newt Gingrich, in the news himself for critical remarks about President Obama's Supreme Court nominee Sonia Sotomayor, is set to headline the joint fundraising dinner for the Senate and House Republican campaign committees.
Gingrich was slotted to replace Palin on the program in March after she and her staff waffled over whether she would accept the speaking invitation, which had already been publicly announced by both the NRSC and the National Republican Congressional Committee. At the time, Palin's office in Alaska said that her political staff in Washington had agreed to the invitation without consulting the governor.
Last week, Palin reached out to the committees through Republican fundraiser Fred Malek to say she would be in Washington on the day of the dinner and would be available to speak. Malek and Cornyn attempted to work out a plan that would allow Palin to make a brief speaking appearance on stage.
But Rep. Pete Sessions, the NRCC chairman, was concerned that Palin might upstage Gingrich, so the governor was later told she would not be able to deliver remarks, but was still welcome to attend.
UPDATE: A GOP official involved in the dinner planning tells CNN that the Alaska governor is "expected to attend" the event "and will be sitting with Sen. John Cornyn and his wife at their table."
The source, who spoke on the condition of anonymity because of internal GOP politics, said she is not expected to make formal remarks but will be recognized during the program.
A Palin spokeswoman refused to confirm whether the governor planned to attend the event.
