Trump, his son, and his staff have all denied that he had prior knowledge of the meeting at Trump Tower. However, Cohen now reportedly claims that he was not only at a meeting when Trump was informed of the planned meeting but others were also present.
Cohen previously testified before two congressional committees investigating Russian interference in the 2016 election and did not reportedly reveal such prior knowledge by Trump.
Such testimony would be exceptionally dangerous for Trump, Trump Jr. and some staffers if Mueller believes that Cohen’s account is true. Mueller has already indicted a slew of individuals for false statements to investigators. This would be an even stronger case for prosecution if the accounts are true.
If Trump Jr. were to be charged, it is difficult to predict President Trump’s response but it would likely be extreme. Of course, taken Cohen’s word alone on such a question is a rather precarious proposition. The question is whether such testimony could prompt other witnesses to come forward or whether Cohen would be left to stand alone.
