Prominent Gibson, Dunn & Crutcher lawyers in Washington and Los Angeles are working with Morrison & Foerster on behalf of Inc. to sue the U.S. Defense Department over its decision to award a $10 billion cloud-computing contract to rival Microsoft Corp.

The Gibson Dunn team on the complaint, filed Friday in the U.S. Federal Claims Court, includes veteran Supreme Court advocate Ted Olson and Theodore Boutrous Jr., whose First Amendment media advocacy has pit him against the Trump administration. Olson, who served as President George W. Bush administration’s top appellate lawyer, earlier this month argued against President Donald Trump’s move to rescind an Obama-era immigration program benefitting 700,000 so-called Dreamers who arrived as children.
