Oh, c'mon. The Democrats were the one counting on Cohen here, not the other way around. You all expected a big "I witness Russia collusion personally, here's A, B and C detailing it", nothing.
He said he's never been to Prague, which has been the closest "smoking gun" moment with all of this Russia stuff. Says he has nothing to back any of the collusion narrative, blah blah.
Look, Cohen's not even a reliable witness in the first place, so anything he says either way has to be taken with a grain of salt, including his "nothing to see here" on Russia. Take Mueller's report, not Cohen's laughable trying-to-save-his-ass.
Also, look up his interviews from dates after he said he's had his big revelation about the President being this corrupt damn dirty racist he didn't want a part of anymore. He literally went on TV after he said he turned on the guy, timeline wise, saying he "didn't want a job a the White House because I'm very happy being Trump's lawyer". The narrative doesn't add up, he didn't have a problem with the way the guy was doing business, post-Charlottesville and all this other **** he's citing.
