Here is what Dr. Nass says about Matsumoto
12. Ivins cursed about giving journalist Gary Matsumoto information requested in a Freedom of Information Act request. Matsumoto is a most peculiar journalist. We had a number of conversations. He would not get off the phone, sometimes staying on for an hour or more. He would harass me, in an attempt to shape the story. He worked very hard, trying to force me to say that the only problem with anthrax vaccine was its squalene adjuvant, although there were many reasons to question that assertion. I hung up on him more than once, exasperated, and no doubt I used some foul language describing our conversations to others.
