US president-elect Donald Trump denied allegations on Wednesday that Russia could have leverage over him, saying on Twitter: "I have nothing to do with Russia - no deals, no loans, no nothing."
Trump, the billionaire businessman who authored a bestselling book in the late 1980s titled "The Art of the Deal," has repeatedly visited Moscow for past ventures, including in 2007 to promote a luxury vodka brand and in 2013 for the Miss Universe beauty contest, which he helped organize.
US media reported Tuesday that Trump as president-elect was recently presented 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.
Ahead of his scheduled press conference in New York, Trump took to Twitter to slam the allegations.
"Russia has never tried to use leverage over me. I HAVE NOTHING TO DO WITH RUSSIA - NO DEALS, NO LOANS, NO NOTHING!"
"I win an election easily, a great "movement" is verified, and crooked opponents try to belittle our victory with FAKE NEWS. A sorry state!" he wrote in another tweet.
"Are we living in Nazi Germany?" Trump asked. "Intelligence agencies should never have allowed this fake news to 'leak' into the public."
The Kremlin quickly denied the rumour, saying it does not have any compromising information about 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.
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.
Trump, who becomes president on January 20, has vowed to rebuild frayed US-Russian ties. The current US leadership under departing President Barack Obama believes that Russian hackers leaked compromising information about the Democratic Party to give Trump, a Republican, an edge in the election.
