Halliburton says it's fired employees who allegedly took kickbacks.
The Wall Street Journal had reported that two employees of a Halliburton subsidiary took as much as six million dollars from a subcontractor in Kuwait that was helping to supply US troops in Iraq.
Halliburton says it's fired the employees, and reported the "irregularities" to the Pentagon and to criminal investigators.
A company spokeswoman says it's the kind of behavior that isn't tolerated at any level.
Halliburton is the company that used to be headed by Vice President Cheney.
The same Halliburton subsidiary, KBR, has been accused of overcharging the government by millions of dollars for fuel deliveries in Iraq. Halliburton denies those charges.
