They write letters (actually, email) that link to this:
Last week President Obama and Secretary Vilsack approved Monsanto’s GMO alfalfa despite overwhelming public protest. This move fundamentally undermines the organic industry, especially organic meat and dairy. In approving GMO alfalfa the Obama administration has caved to Monsanto and made it harder for family farmers to make a living and for consumers wanting to eat safe, healthy foods.
Shake a finger at Monsanto and the Prez at the link.
