The documents I think provide a level of clarity about this. In my testimony last week and this week, I spoke to the fact that we went to the Public Health Agency and the lab to share with them our concern about an insider threat specifically about the type of environment they're in. It's at that point that they raised specific issues with those two individuals. We launched our investigation at that point.
In response to Mr. Naqvi, I mentioned that from that time until the moment we were able to provide very clear indicators of significant national security concerns, it was done in a fairly tight time frame.
