Russia's permanent mission to the UN has received a letter from U.S. Republican presidential candidate John McCain asking for financial support of his election campaign, the mission said in a statement on Monday.
'We have received a letter from Senator John McCain with a request for a financial donation to his presidential election campaign. In this respect we have to reiterate that neither Russia's permanent mission to the UN nor the Russian government or its officials finance political activities in foreign countries,' the statement said.
According to Ruslan Bakhtin, press secretary of the Russian mission, the letter dated September 29 and signed by McCain, was addressed to Vitaly Churkin, Russia's envoy to the UN, and arrived on October 16.
