HELENA, Mont. (AP) — U.S. Sen. John Walsh of Montana says he was on medication and being treated for post-traumatic stress disorder when he used unattributed work of scholars in his master's thesis.
Walsh says he unintentionally made incorrect citations in the 2007 paper, written nearly two years after he returned from Iraq.
Walsh told The Associated Press on Wednesday that his "head was not in a place very conducive to a classroom and an academic environment."
He was being treated and taking medication for persistent nightmares, anxiety, sleeplessness and the recent suicide of another veteran.
He says he has worked through those issues, though he is still taking antidepressant medication. Walsh says he will consider apologizing to the scholars for lifting their work.
