from virginia, you are on with dustin volz. forer: hey, think you taking my call. do you have any idea why it has taken so long for congress to finally get involved in this? that is basically it. i know before president obama came into office, there had been a whole lot of backwards activity on twitter and facebook and google. i just wonder why it is taking them so long to get to the bottom of this. thanks. guest: that's a great question. means to question that be asked of congress and the people investigating this. congress asked this week of the technology companies, which came forward and said, facebook said we had 126 million people who may have seen russia election political material during the an enormousich is revision upward of what they previously said, and that was after the ceo mark zuckerberg said it was a crazy idea that it happened at all. these investigations are complex. there is a lot that takes a long time. but absolutely, it is something that can be aggravating to people that, more than a year later, we're still talking about just what russia did.
