Defense Secretary Mark Esper said he heard questions from people in the White House about a Pentagon cloud-computing contract valued at as much as $10 billion, but wasn't directed to order the review that's under way.

President Donald Trump stunned technology companies, the Defense Department and lawmakers in July when he openly questioned whether the pending contract is being competitively bid amid concern the deal favors Inc.'s cloud unit.

Esper, who has recently taken over the department, ordered the review of the contract for the Joint Enterprise Defense Infrastructure cloud, also known as JEDI, on Aug. 1.
