Todd Blanche apparently has so far conducted a rambling and confusing cross examination of Cohen, and at some point during that cross he grew frustrated and lost his crap. Todd 'crying little chit' Blanche got angry and accused Cohen of lying without having any evidence of that. It was a dramatic moment because Blanche raised his voice and shrieked. But it probably means nothing to the jury except that they lost any remaining respect they may have had for Blanche. Everything Cohen has testified to, is already backed up by other evidence or testimony. Poor Blanche had to make a scene to please his client the criminal defendant.
