How much longer do you think the U.S. will survive?

Rumsfeld served as Gilead (Research)'s chairman from 1997 until he joined the Bush administration in 2001, and he still holds a Gilead stake valued at between $5 million and $25 million, according to federal financial disclosures filed by Rumsfeld.

The forms don't reveal the exact number of shares Rumsfeld owns, but in the past six months fears of a pandemic and the ensuing scramble for Tamiflu have sent Gilead's stock from $35 to $47. That's made the Pentagon chief, already one of the wealthiest members of the Bush cabinet, at least $1 million richer.

Rumsfeld isn't the only political heavyweight benefiting from demand for Tamiflu, which is manufactured and marketed by Swiss pharma giant Roche. (Gilead receives a royalty from Roche equaling about 10% of sales.) Former Secretary of State George Shultz, who is on Gilead's board, has sold more than $7 million worth of Gilead since the beginning of 2005.

Another board member is the wife of former California Gov. Pete Wilson.

"I don't know of any biotech company that's so politically well-connected," says analyst Andrew McDonald of Think Equity Partners in San Francisco.

What's more, the federal government is emerging as one of the world's biggest customers for Tamiflu. In July, the Pentagon ordered $58 million worth of the treatment for U.S. troops around the world, and Congress is considering a multi-billion dollar purchase. Roche expects 2005 sales for Tamiflu to be about $1 billion, compared with $258 million in 2004.

Rumsfeld recused himself from any decisions involving Gilead when he left Gilead and became Secretary of Defense in early 2001. And late last month, notes a senior Pentagon official, Rumsfeld went even further and had the Pentagon's general counsel issue additional instructions outlining what he could and could not be involved in if there were an avian flu pandemic and the Pentagon had to respond.

As the flu issue heated up early this year, according to the Pentagon official, Rumsfeld considered unloading his entire Gilead stake and sought the advice of the Department of Justice, the SEC and the federal Office of Government Ethics.

Those agencies didn't offer an opinion so Rumsfeld consulted a private securities lawyer, who advised him that it was safer to hold on to the stock and be quite public about his recusal rather than sell and run the risk of being accused of trading on insider information, something Rumsfeld doesn't believe he possesses. So he's keeping his shares for the time being.
