Federal fraud busters invited the news media to visit their new $3.6 million command center and watch staffers explain how they'll jump on unfolding Medicare scams. More than $60 billion a year is lost to fraud. And two Republican senators immediately questioned whether the new multimillion-dollar facility is just throwing more money away. Sens. Orrin Hatch of Utah and Tom Coburn of Oklahoma said the Obama administration isn't providing enough information about new computer systems being used to identify suspicious Medicare and Medicaid billings and as a result, no one can tell how well they're working.
