(Washington, DC)  --  Senator Ron Wyden is among a group of Democrats calling the Republican tax reform bill a "GOP tax scam."  Wyden and two other senators took turns slamming the bill in their weekly address.  They say corporations are using their new tax savings on 120-billion-dollars in stock buybacks that only benefit corporate executives and shareholders.  Wyden points out that employee pay boosts, meanwhile, have added up to only about five-billion-dollars.
