looks like lawmakers have found a way around the congressional ban on pork projects, taking advantage of a roughly billion dollars put aside in a special fund. so how's it work? cnn's senior congressional correspondent dana bash takes a look. >> reporter: red stone arsenal in northern alabama, home of army rocket and missile programs, it could get $2.5 million added to a defense bill to developed unmanned vehicle technology thanks to congressman mo brooks who represents the district. that is probably going to go to your district and help your constituents. >> i can't say it's going to go to the fifth congressional district but i will say if that is a service we can offer to america i'll be tickled pink. >> reporter: brooks boasted about getting more jobs for his district. that sounds like an earmark which the house banned this year. what is this all about? watchdog groups worry it's a back doorway around the ban.
