MK Amir Peretz's campaign staff on Wednesday invited Labor leadership candidate Isaac Herzog to a meeting Peretz's office on Thursday.
Earlier Wednesday, Herzog released a statement vigorously refuting a report in the Ha'aretz newspaper that he had made statements to an American diplomat that were racist.
"It is not appropriate to clarify this issue on the telephone. Amir Peretz intends to invite Herzog to a meeting tomorrow," the statement said.
The newspaper published an unsourced, anonymous quote it claimed came from an American diplomat via WikiLeaks that during the 2006 election campaign.
According to the report, Herzog said that Peretz, who was Labor's candidate for prime minister, was perceived as "an aggressive, inexperienced, and Moroccan" but that Labor's list for the Knesset had Ashkenazim that balanced out the Sephardim.
