Virtually without dissent, the House conferees accepted a bipartisan Senate provision written by Charles Grassley, an Iowa Republican, and Ron Wyden, an Oregon Democrat, stipulating that the program cannot be used against American citizens. The conferees also agreed to end research on the program — in effect shutting it down — in 90 days unless the Pentagon submits a detailed report on the program's cost, goals, impact on civil liberties and prospects for success against terrorists. What this means, in effect, is that if the program continues at all, it will be as a low-intensity research project under close Congressional supervision.
