i want to bring in nbc's national security reporter julia ansley, okeydoke, has this cross-examinationso much damage to gates' credibility? >> reporter: i think it puts a dents in his credibility. it remains to be seen if that will put a dents in the prosecution case, though. it seems for a large part of yesterday they were presenting a man shoo would not presenting a life to the jury. this is a man who was able to have a flat in london for his terrorist trysts. and it's unclear, why he kind of still seems squirrelly. and if he was there to fell the truth, as he just put out from that transcript, why wasn't he being more direct? why wasn't he being more remorseful? it may be that the jury is going to have a hard time believing but the prosecution, when they first started questioning him they were able to bring out a number of documents to corroborate great point by point, everything he was saying, the money he was moving illegally through the company that he ran with paul manafort. the lies that were told, they were able to corroborate all of that. we'll see what the defense will do to
