Cohen's alleged claim about Trump Tower is/was a huge story. Lanny Davis suggests there might be problems with that story (which CNN broke). Don Lemon doesn't ask him to explain.
This got buried today, but Burr and Warner said that they contacted Cohen's attorneys after the Trump Tower report. They said he stood by testimony that he did not know about TT meeting until news reports. 
To clarify, they contacted him after CNN's July 27 report that Cohen is willing to tell Mueller that Trump knew about TT meeting beforehand. Cohen had Guy Petrillo and Lanny Davis as legal counsel by that point.
