The JEDI saga continues with a new letter from Senate Democrats asking Secretary Mark Esper about his decision to review the contract.

Mark Esper's "examination" comes after a host of Republican lawmakers asked him and other administration officials to delay the award of the contract.

Sen. Marco Rubio wrote a second letter to the Trump administration asking for a delay in the JEDI contract. A dozen House Republicans wrote a similar letter Tuesday.

Rubio wrote a letter to national security adviser John Bolton saying he worries the single-award contract will "result in wasted taxpayer dollars and fail to provide our warfighters with the best technology solutions."
