An anti-smoking organization plans to file a complaint today with the Federal Election Commission accusing the major tobacco companies of making illegal corporate campaign contributions by promising to run political advertisements on behalf of Republican senators. The complaint, prepared by Campaign for Tobacco-Free Kids, refers to news media accounts of a comment made by Senator Mitch McConnell of Kentucky to his Republican colleagues at a private meeting. According to the accounts, McConnell told his fellow senators if they voted to kill comprehensive tobacco legislation, the cigarette manufacturers would run TV advertisements supporting them. A few hours after that meeting, the Senate fell three votes short of approving a motion to cut off debate on the tobacco bill. Forty of the 42 votes against ending debate came from Republicans. The effect of the vote was to scrap the legislation.
