Service Employees International Union chief Andy Stern is lobbying for healthcare reform on Capitol Hill today with an out of town guest.

He tweeted:
Lobbying with Mayor Bloomberg on health care. Leaving Senator Snowe. Mayor big proponent of keeping people healthy and the right public plan

New York Mayor Michael Bloomberg, like Stern, is a noted supporter of healthcare reform. The duo's visit with Sen. Olympia Snowe (R-Maine) raises eyebrows. Reform proponents may need support from both sides of the aisle in order to pass the legislation through the Senate.
