n February 2011, journalist Michael Hastings reported in Rolling Stone that Lt. Colonel Michael Holmes, the supposed leader of a PSYOP group in Afghanistan, alleged that Lt. Gen. William B. Caldwell a three-star General in charge of training troops in Afghanistan, ordered Holmes and his group to perform in-depth research on visiting U.S. congressmen in order to spin presentations and visits. According to Holmes, his team was tasked with "illegally providing themes and messages to influence the people and leadership of the United States." Reported targets included United States Senators John McCain, Joe Lieberman, Jack Reed, Al Franken, Carl Levin, Rep. Steve Israel of the House Appropriations Committee; Adm. Mike Mullen of the Joint Chiefs of Staff; the Czech ambassador to Afghanistan; the German interior minister, and think-tank analysts.
Under the 1948 Smith–Mundt Act, such operations may not be used to target Americans. When Holmes attempted to seek counsel and to protest, he was placed under investigation by the military at the behest of General Caldwell's chief of staff.
but this has changed, right? with the revoking of the Smith-Mundt Act the Military can now target Americans with PSYOPS
interestingly, Gen Lloyd Austin is a Mliltary PSYOP specialist and has written for instance this
