The U.S. Senate yesterday approved spending $4.6 billion to settle two lawsuits: one by black farmers who alleged racial discrimination by government lenders and the other by 300,000 American Indians who said they had been cheated out of land royalties dating to 1887. Passage of the measure, by voice vote, unblocks a legislative logjam that has thwarted payouts, negotiated by the Obama administration, of $1.15 billion to the black farmers and $3.4 billion to the American Indians. The House ... must vote on the settlements again. At least seven times this year, Senate Republicans blocked efforts to include the spending provisions in pending legislation. The farmers' 1997 class-action lawsuit alleged discrimination by the Agriculture Department's lending programs. Under a negotiated settlement announced in February, qualified farmers can collect as much as $50,000, plus debt relief. Others may collect monetary damages up to $250,000. One of the largest class-action cases filed against the U.S., the 1996 lawsuit by American Indian plaintiffs accused the Interior Department of mismanaging trust funds that collected royalties for grazing rights and the extraction of minerals, oil and natural gas from tribal lands.
