An allegation that Russia has compiled a compromising dossier on US president-elect Donald Trump is a "complete fabrication and utter nonsense" according to a spokesman for President Vladimir Putin.
"This is an evident attempt to harm our bilateral ties," Kremlin spokesman Dmitry Peskov added.
An American official said on Tuesday that intelligence officers had informed Trump about an unsubstantiated report that Russia had compromising personal and financial information about him.But after news reports were published about that briefing, Trump tweeted (using capital letters): "Fake news - a total political witch hunt!"
In dismissing the report in a less rowdy manner, Peskov remarked that the allegations could be an attempt to rein in US politicians who want to improve ties with Russia.
"We should treat it with humor, but there is a sad side to it, too," he added.
"There are people who are whipping up this frenzy, who are doing their best to keep this witch hunt going."
Peskov described the report, which included claims of Trump romping with prostitutes in a Moscow hotel, as part of efforts to "keep harming relations"
