The Kremlin said Wednesday that it does not have any compromising information on US president-elect Donald Trump.
Reports alleging otherwise are an "absolute fabrication," Kremlin spokesman Dmitry Peskov said in comments carried by state media.
Such reports are akin to "pulp fiction," Peskov said. "The Kremlin does not collect compromising information."
He also denied having compromising information on Hillary Clinton, Trump's rival in November's presidential election.
US media reports said Trump was presented last week with classified documents by US intelligence that Russia might have compromising information about him, including possible sex videos from a visit to Moscow.
A synopsis of the allegations was attached to the end of a report by US intelligence agencies on Russian interference in the US elections, broadcaster CNN reported.
Trump, who was scheduled to hold a news conference on Wednesday, reacted on Twitter: "FAKE NEWS - A TOTAL POLITICAL WITCH HUNT!"
A former head of the Russian federal security service, the FSB, the main successor of the Soviet KGB, denied on Wednesday that Russia has any compromising information on Trump.
"There is, of course, no compromising information," Nikolai Kovalyov, who headed the FSB in the late 1990s and is currently a lawmaker in Russia's lower house of parliament, said in comments carried by the Interfax news agency.
