edit: I summed the years and got $5.3 million since 2007. The UI doesn't seem to help you sum at all.

excerpt from WSJ article included:
"Mr. Matlack is president of American Agriculture Movement, a farmers' advocacy group that was listed among about 40 members of American Task Force Argentina, whose stated mission is to help investors recoup money from Argentina's 2001 bond default and subsequent restructuring.
"But Mr. Matlack and some leaders of other groups representing ranchers, teachers and farmers, are baffled about why the task force listed their organizations as members 'united for a just and fair reconciliation' of Argentina's default.
"Reached while he was planting wheat on his farm, Mr. Matlack said he had never heard of American Task Force Argentina. 'We don't have anything to do with Argentina's debt,' he said.
"Also perplexed are leaders of the Colorado conference of the American Association of University Professors, which was listed under members and supporters. 'This is absolutely foreign to me,' says Ray Hogler, legislative director of the academic group.
"Both groups were dropped from the list after the Wall Street Journal alerted the task force to the discrepancies."
