What my research shows and what I have done in practice demonstrate that terrorist groups around the world raise money from a variety of different activities, but one of the ways they do it is by taxing aid organizations that operate in their area. That could look like acquiring resources from them. It could look like taking a certain percentage of the money that comes into the country.
Part of my concern with not having a broad humanitarian exemption here is a complete inability to calibrate that. We don't have the ability to help aid organizations, for instance, prevent that from happening. We don't have a way to understand how much money or how many resources are going to terrorist organizations when they operate—
