In his early years in Congress, he often issued press releases critical of shortcomings he detected in the armed forces. In 1973, he criticized the Air Force for devising a plan to purchase 200 beagle puppies, tie the dogs' vocal cords, and conduct tests of poisonous gases. After Aspin began a publicity campaign against the Air Force's plan, an outraged public sent a record number of letters to the Defense Department, surpassing the amount ever sent about any other subject. In March 1974, Aspin told an audience at Brown University, including future 4-star General Wesley Clark and four West Point cadets: "You, the young officer and cadets sitting there - never in your lifetimes will you see us intervene abroad. We've learned that lesson."
