After nearly a year of stonewalling, security clearances have finally been approved by the White House so that the Department of Justice can investigate its own involvement in the NSA's warrantless surveillance program.  I look forward to the results of this inquiry.  Congress needs to craft legislation so that terrorists can be the subject of surveillance while the Constitution of the United States is honored. To do that a full investigation into the program as a whole, not just the DOJ's involvement, will be necessary.
