(CNN) - John McCain’s campaign seemed to accuse Barack Obama of pressuring Hillary Clinton to withdraw from appearing at a rally with Sarah Palin, and pushing the group to disinvite the Alaska governor – but did not provide reporters any evidence to back up the claim.
Late Tuesday, an organizer of the September 22 “Stop Iran. Now!” rally announced that Clinton, Palin and Nobel Laureate Elie Wiesel would be appearing at the event. Hours later, Clinton’s office announced that had changed her decision, and would not attend.
“Earlier this week Governor Palin accepted an invitation to join Hillary Clinton in speaking to a nonpartisan rally organized by groups dedicated to halting Iran's nuclear program,” said McCain-Palin spokesman Michael Goldfarb said in a statement. “Senator Clinton has since withdrawn from the engagement, presumably at the behest of the Obama campaign, and according to news reports, Senator Obama's campaign may be leaning on organizers to disinvite Governor Palin as well lest the rally appear partisan.”
But the Politico story cited by Goldfarb in an e-mail sent to reporters does not include any sources making that charge. One anonymous source – who is identified only as someone “familiar with the talks” – seems to reference debate among organizers over whether or not an Obama-Biden representative was needed if Palin attended the rally in New York over Iran’s nuclear program, to avoid the appearance of partisan politics. It does not mention any request of this kind coming from anyone connected to the Obama-Biden campaign, including Senator Obama himself.
“This issue is too important to fall victim to partisan politics,” Goldfarb also wrote. “Instead of pressuring Senator Clinton to withdraw and pressuring the event's organizers to disinvite Governor Palin, we hope Senator Obama will consider lending his own voice to this cause….”
There has been no mainstream media report or public claim by anyone in Clinton’s camp that she received any pressure from the Obama campaign not to appear at the rally, as Goldfarb implies. Clinton spokesman Philippe Reines said early Wednesday that Palin’s presence at the event and the appearance of partisan politics was the reason for Clinton’s withdrawal.
"Her attendance was news to us, and this was never billed to us as a partisan political event,” said Reines. “Senator Clinton will therefore not be attending."
The McCain campaign has not yet responded to a CNN request for the source of the apparent allegations.
