And we move on next to a class action lawsuit that has the attention of a lot of americans. It is about beer. The charge is that budweiser allegedly watered down some of its beer. The company says no. Abc's linzie janis tells us more. Reporter: Is the king of beers shortchanging its subjects? Lawsuits filed in four states are accusing an huzer bush of being, well, buzz killers. The legal filings say anheuser-busch is falsely representing the alcohol content of its products, by watering down their beers by as much as 8% of the amount stated on the label. The lawyer representing the allegedly betrayed beer drinkers says he has more than a dozen former anheuser-busch employees that say they witnessed or were involveed in the process. As it's running down the line to go into the bottles and cans they add water to it to dilute it bow the stated alcohol content on the label. Reporter: The whistle blowers haven't come out publicly and no tests have been performed, but these lawyers have won cases against corporate giants before. Anheuser-busch called the claims completely false, and groundless. Beer drinkers are a very loil crowd. It may make them question things. Reporter: Makers mark learned that the hard way. Public outcry forced it to change course of announcing it would dlut its trademark bourbon. Brewers have to be consistent and put out the same thing over an over. Reporter: And if anheuser-busch wants its customers to be consistent, it will need to convince them they can trust what's inside. Linzie janis, abc news, new york.
