From MSNBC:

Republican Sen. Orrin Hatch has taken himself out of bipartisan group of Finance Committee members drafting the health-care bill.
”Some of the things they’re talking about, I just cannot support. So I don’t want to mislead anybody,” he told reporters moments ago.
Left in the group — which met this morning without Hatch — are Max Baucus (D-MT), Jeff Bingaman (D-NM), Kent Conrad (D-ND), Olympia Snowe (R-ME), Mike Enzi (R-WY), and Chuck Grassley (R-IA).
