In March 1993, U.S. Senator Tom Harkin (D-Iowa) proposed legislation to eliminate the deduction of advertising as a business expense for tobacco companies.
In true prohibitionist fashion, Harkin seeks to penalize the makers of tobacco products for daring to hold a belief contrary to his own.
The ACLU condemned the proposal, citing Supreme Court decisions forbidding Congress from discriminating in policy on the basis of speech content.
