He was appointed with a fair bit of fanfare as the United States' first Chief Technology Officer back in May of 2009, but it looks like Aneesh Chopra has decided that it's now time to make room for the nation's second CTO. The White House confirmed today that Chopra is stepping down from his position, noting that he has amassed a "dizzying array of accomplishments." Among those are his contributions to the Obama administration's national wireless strategy, a set of internet policy making principals, and a number of efforts related to the President's open government strategy, including the Data.gov platform. No word on his successor just yet, nor is there any official word on what Chopra plans to do next -- although The Washington Post reports that he's expected to run for lieutenant governor of Virginia.
