"Halliburton admits to criminal probe on Iran," the FT reports:
Halliburton, the oilfield services company formerly headed by US vice-president Dick Cheney, has disclosed that a Treasury department probe into its business dealings with Iran had been elevated to a criminal investigation.
The company acknowledged that it had been subpoenaed by a grand jury in the southern district of Texas to present documents related to a Cayman Islands subsidiary that serves the Iranian National Oil Company . . .
The US imposed sanctions on Iran following the 1979 revolution that led to the seizure of American hostages for more than a year.
Halliburton's work there, which has raised complaints from shareholders, amounts to about $80m a year - less than 1 per cent of its total revenues.
I guess some people were advocates of engagement a little earlier than others.
Update: Mitch Cohen is following this case closely, and has more here. Apparently Cheney was indeed CEO when Halliburton got involved in the business of oilfield development in Iran in 1997.
