According to "Newsweek", "Under Negroponte, the intel czar's office was praised by both congressional and executive-branch officials for greatly improving—via its National Counterterrorism Center—the sharing among relevant agencies of intelligence reports about terror threats." Negroponte was sworn in as U.S. Deputy Secretary of State by President George W. Bush on February 27, 2007. He served in that position until the end of the Bush administration on January 20, 2009. Ambassador Negroponte joined McLarty Associates, an international strategic advisory firm headquartered in Washington, D.C., in 2009. He serves on the Leadership Council of Concordia, a nonpartisan, nonprofit based in New York City focused on promoting effective public–private collaboration to create a more prosperous and sustainable future. Negroponte was one of 50 signatories of a statement concerning 2016 Republican presidential candidate Donald Trump in which Trump was called "reckless" and stated that he would "put at risk our country's national security and well-being."
