State Attorneys General have formed a task force (the Anti-Robocall Litigation Task Force) to fight back against illegal robocalls. They are undertaking specific campaigns, such as Operation Robocall Roundup, to warn and potentially take legal action against telecommunications companies that are not doing enough to prevent these unwanted calls.
