(Reuters) -The U.S. Department of Justice plans to allege that Visa (NYSE:) illegally monopolized the country’s debit card market, Bloomberg News reported on Monday.

The antitrust division is set to file a lawsuit in federal court as early as Tuesday, accusing Visa of various anticompetitive behaviors, the report said, citing unnamed sources.

Antitrust enforcers are preparing to accuse Visa of taking measures to prevent competitors from challenging its dominance in the debit card market, according to the report.
