OCONOMOWOC, WI (WTAQ) - A video of Tommy Thompson referring to September 11th as September 18th has gone viral.

The comments come from statements he made June 4th to the Lake Country Area Defenders of Liberty in Oconomowoc.

Thompson touted why he is the most qualified to be Wisconsin's next U.S. Senator and discussed his time as U.S. Health and Human Services Secretary during the 9-11 attacks.

He says, "And then after 9/18, I was responsible for the public health of all Americans, responsible for preventing any attack using weaponized medicines like the plague, like smallpox, like anthrax, like tellurium."

The Huffington Post is showing the clip.

Thompson spokesman Brian Nemoir says in a statement to other media outlets, "as a point of clarification, 9/18/01 is in reference to the anthrax attacks on specific members of congress and varied members of the news media. In-total, it is believed that seven letters were mailed containing anthrax spores, contaminating 22 people of which five people died. As Secretary of the Department of Health and Human Services, Tommy Thompson lead the efforts to protect our nation from these bio-threats."
