An economic development director at Amazon.com Inc. isn\u2019t happy about a Washington Post report that the e-commerce giant is in advanced talks with a Washington suburb about being the location for its second headquarters. In a tweet Saturday morning, Amazon\u2019s Mike Grella addressed \u201cthe genius leaking info,\u201d saying: \u201cYou\u2019re not doing Crystal City, VA any favors. And stop treating the NDA you signed like a used napkin.\u201d Grella didn\u2019t say who he thought leaked the information, nor did he address the story itself. Mike Grella@MikeGrella Memo to the genius leaking info about Crystal City, VA as #HQ2 selection. You\u2019re not doing Crystal City, VA any favors. And stop treating the NDA you signed like a used napkin. cnbc.com\/2018\/11\/03\/ama\u2026 In earlier tweets, Grella criticized another story in the Post - owned by Amazon founder and CEO Jeff Bezos - for speculating about the possible second headquarters location based on flight patterns of Bezos\u2019 jet. \u201cThe search team has earned his trust and the highest use of his time isn\u2019t looking at vacant buildings and land - he has a company to run,\u201d Grella wrote. Mike Grella@MikeGrella as an Amazon spokesman said, where Jeff flies to and doesn\u2019t fly to says nothing about #HQ2 cities. The search team has earned his trust and the highest use of his time isn\u2019t looking at vacant buildings and land- he has a company to run. -#Amazon washingtonpost.com\/business\/where\u2026 If a company\u2019s location intent was judged by where its CEO flies, Grella said in a follow-up tweet, Amazon might also go to Davos, Switzerland; Sun Valley, Idaho; Rome or Hollywood, and Google, Facebook and Tesla might be relocating to \u201cBlack Rock Desert, NV," a reference to the annual Burning Man cultural festival. Grella doesn\u2019t have direct knowledge of the headquarters search and negotiations, according to a person familiar with the process. Bud Perrone, a spokesman for JBG Smith, Crystal City\u2019s top developer, declined to comment. Amazon in 2017 announced plans to invest $5 billion and hire 50,000 people over the next 18 years. A decision is scheduled by the end of the year, with 20 cities in the U.S. and Canada in the running. The search has prompted months of speculation about the most likely winner. Many experts have named the Washington area as a front-runner given Bezos\u2019 ownership of the Post and the company\u2019s stepped-up lobbying efforts. Crystal City is a neighborhood in Arlington, Virginia, just across the Potomac River from the nation\u2019s capital, that features a concentration of high rise offices, hotels and residential buildings.
