I shall repeat: a total of one case in which the plaintiff claims fast food made them obese has ever been filed in this country. It was thrown out of court. It did not go to trial, the defendant did not have to waste any time and/or money proving the case was frivolous.

I don't think a total of one case, which by the way was thrown out of court and didn't make it to trial, is grounds for passing legislation to ban any future cases on the matter.

Congress shouldn't be in the business of saying what the courts are and are not allowed to bring to trial. That's up to the courts.
