Daniel Sarewitz’s editorial in Nature is here. I completely agree with it. Money quote:
To connect scientific advice to bipartisanship would benefit political debate. Volatile issues, such as the regulation of environmental and public-health risks, often lead to accusations of ‘junk science’ from opposing sides. Politicians would find it more difficult to attack science endorsed by avowedly bipartisan groups of scientists, and more difficult to justify their policy preferences by scientific claims that were contradicted by bipartisan panels.
