Senators Revive Bill to Break Big Tech’s Grip on Pentagon Deals

A bipartisan pair of senators is reviving a bill to break the grip that tech giants like Amazon.com Inc., Microsoft Corp. and Alphabet Inc.’s Google have on the Pentagon’s cloud computing and artificial intelligence contracts.

The Protecting AI and Cloud Competition in Defense Act is set to be reintroduced on Thursday by Democratic Senator Elizabeth Warren of Massachusetts and Republican Eric Schmitt of Missouri, according to people familiar with the matter. A version of the bill is also being introduced for the first time in the House, said the people, who spoke on condition of anonymity as the information is not public.
