Lanny Davis, a spokesman and attorney for Cohen, said in an interview this weekend that he is no longer certain about claims he made to reporters on background and on the record in recent weeks about what Cohen knows about Trump’s awareness of the Russian efforts.

Davis did not rule out that his claims were correct but expressed regret that he did not explain that he could not independently corroborate them, saying that he now believes he “should have been more clear.”…

Davis told The Washington Post that he cannot confirm media reports that Cohen is prepared to tell special counsel Robert S. Mueller III that Trump had advance knowledge of the 2016 Trump Tower meeting, where Donald Trump Jr. expected to receive damaging information about Clinton from a Russian lawyer.
