"The company believes it has acted properly and has not committed any wrongdoing," he said, according to the report.
The investigation reflects growing concern among Justice Department and Treasury officials that casinos might be used for money laundering, the newspaper said.

Adelson is a large donor to a super PAC that supports Republican presidential candidate Mitt Romney.
