Michael Cohen took to Twitter Thursday to deny a McClatchy report alleging that a cell phone traced to the former Trump lawyer had pinged a cell tower in Prague in the summer of 2016 during the U.S. presidential campaign. The unconfirmed McClatchy report supports a claim made in the infamous Steele dossier—which Trump has derided as “a pile of garbage”—that Cohen secretly met with Russian officials in Prague. But Cohen appeared to deny those charges in his Thursday tweet: “I hear #Prague #CzechRepublic is beautiful in the summertime,” he wrote. “I wouldn’t know as I have never been. #Mueller knows everything!” Earlier this December, Cohen was sentenced to three years in prison for crimes including lying to Congress, and making hush-money payments to women who claimed they’d had affairs with then-candidate Donald Trump.
