The document also makes specific claims about contacts between people working for Trump and Russian officials. It alleges that Michael Cohen, special counsel to Trump, was central to “the ongoing secret liaison relationship between the New York tycoon’s campaign and the Russian leadership,” and that he met secretly with Kremlin officials in Prague in August 2016.

Reached by telephone on Tuesday night, Cohen denied the dossier’s allegations.

The story is “totally fake, totally inaccurate,” Cohen said.

“I’m telling you emphatically that I’ve not been to Prague, I’ve never been to Czech [Republic], I’ve not been to Russia,” Cohen said. “The story is completely inaccurate, it is fake news meant to malign Mr. Trump.”

Cohen said that during the time the report places him in Prague, he was actually with his son visiting USC and meeting with the baseball coach. A USC baseball source confirmed Tuesday night that Cohen and his son had visited USC on August 29th. Cohen said that he was in Los Angeles from the 23rd through the 29th of August, and that the rest of the month he was in New York. He said that his only trip to an EU country over the summer had been a vacation to Italy in July.
