The man, who called himself Henry Greenberg, offered damaging information about Hillary Clinton, Trump’s presumptive Democratic opponent in the upcoming presidential election, according to Stone who spoke about the previously unreported incident in interviews with The Washington Post. Greenberg, who did not reveal the information he claimed to possess, wanted Trump to pay $2 million for the political dirt, Stone said.

“You don’t understand Donald Trump,” Stone recalled saying before rejecting the offer at a restaurant in the Russian-expat magnet of Sunny Isles, Fla. “He doesn’t pay for anything.”

Later, Stone got a text message from Michael Caputo, a Trump campaign communications official who’d arranged the meeting after Greenberg had approached Caputo’s Russian-immigrant business partner.
