WASHINGTON, DC (KDAL) - A bill co-authored by Minnesota U-S Senator Amy Klobuchar that would ban dangerous synthetic drugs is being blocked from a final vote. Klobuchar says the measure has bipartisan support and a similar bill has already passed the U-S House but Senator Rand Paul has put a hold on the proposals because of his concerns about the far reaching consequences of federal drug laws. Klobuchar says his objections deserve to be heard but a period of debate needs to be followed by a vote. She calls it a "life and death" issue since the availability of these synthetic drugs are putting peoples lives at risk and says "it's time to act".
