The issue covered by the bill is how professional fund raisers solicit donations for charities.
The Judiciary Committee endorsed it on a voice vote Monday. The action forwards the bill to the Senate, which could vote on it this week.
The bill requires solicitors to tell the people they call that they work for a professional fund raising company up front.
Then, if the donor wants information about how much money actually goes to charity, the solicitor must disclose it.
The measure's sponsor, Senate Majority Leader Derek Schmidt, an Independence Republican, wanted to go further, but the attorney general's office raised free speech questions.
