<A HREF="http://news.yahoo.com/s/ap/20080401/ap_on_hi_te/ibm_contract_ban">IBM's ban from all new federal work</A> stems from an $84 million Environmental Protection Agency contract the company lost last year and is protesting. The EPA last week temporarily banned IBM from receiving any new government contracts while it investigates "potential activities involving a procurement." IBM said it is also cooperating with the U.S. Attorney's Office for the Eastern District of Virginia, which served grand jury subpoenas seeking documents and testimony relating to interactions between agency and IBM employees.
