NBC Montana talked to Sen. John Walsh on Friday about his post-traumatic stress disorder (PTSD), which he said he suffered from while attending the Army War College.
He said it still flares up from time to time, and he takes medication to treat the symptoms.
When we asked about his Master's thesis, and accusations he plagiarized huge portions of it, Walsh wanted to make one thing clear -- that PTSD has nothing to do with the alleged plagiarism.
"I want to make it very clear that the mistake that I made while I was at the War College had nothing to do with the issues that I was suffering from in Iraq," he said, adding, "Was I in a good academic mindset to be at the War College? Maybe not."
He later reiterated, "They're not related. No, not at all."
The statement conflicts with what Walsh apparently said just two days before. The Associated Press quoted Walsh as saying, "I don't want to blame my mistake on PTSD, but I do want to say it may have been a factor."
NBC Montana wasn't able to ask Walsh follow-up questions because he was limited on time and had to end the interview after his remarks to leave for another event.
While Walsh is not denying the plagiarism accusations, he is saying it was an unintentional mistake and not done on purpose.
So far, he has yet to apologize.
