On Saturday, President Donald Trump’s personal attorney responded to allegations that he was in Prague while Trump was campaigning during the 2016 election cycle.

In a tweet, Michael Cohen wrote: “Bad reporting, bad information and bad story by same reporter Peter Stone @McClatchyDC. No matter how many times or ways they write it, I have never been to Prague. I was in LA with my son. Proven!”

The allegations, which were first made over a year ago, resurfaced on Friday in a report that stated Special Counsel Robert Mueller had proof that Cohen was in Prague.

McClatchy DC reports:

The Justice Department special counsel has evidence that Donald Trump’s personal lawyer and confidant, Michael Cohen, secretly made a late-summer trip to Prague during the 2016 presidential campaign, according to two sources familiar with the matter.

Confirmation of the trip would lend credence to a retired British spy’s report that Cohen strategized there with a powerful Kremlin figure about Russian meddling in the U.S. election.

In January 2017, CNN’s Jake Tapper reported that the allegations were false, saying that government officials confirmed to him that it was a different Michael Cohen in Prague, not Trump’s lawyer.
