US spy chiefs have informed Donald Trump that Russian operatives claim to possess deeply compromising personal and financial information about him, US media reported Tuesday on the eve of the president-elect's first press conference. Trump denounced a "political witch hunt" after CNN reported that intelligence officials briefing him last week on allegations of Russian meddling in the US election had also given him a synopsis of the explosive and unverified claims.
