Michael Cohen demanded an apology for the misreporting of his links to Russia, emphatically tweeting "I had nothing to do with Russian collusion or meddling!"
The unverified dossier authored by former British spy Christopher Steele fingered Cohen, former attorney for President Donald Trump, as a key cog between the Trump campaign and Russians.
The dossier said Cohen had been in Prague for a secret meeting, a charge Cohen has steadfastly denied.
Cohen is in the throes of an investigation by the Southern District of New York after raids on his home and office in April. He has yet to be charged.
