The Pentagon is hitting pause on awarding its $10 billion cloud computing contract until the Defense Department examines whether the process was rigged in favor of Amazon, according to Business Insider.

“Keeping his promise to Members of Congress and the American public, Secretary Esper is looking at the Joint Enterprise Defense Infrastructure (JEDI) program,” a Pentagon spokesperson said in a statement Thursday. “No decision will be made on the program until he has completed his examination.”

The contract was supposed to be awarded sometime this month.
