An Amazon executive may have inadvertently given away the location of the online retail giant’s second headquarters after taking to Twitter to slam a Washington Post report that named a Virginia city as the likely winner. After the Post cited sources close to the situation on Saturday to say Amazon executives had begun holding “advanced discussions” on setting up shop in Crystal City, a residential area south of Washington, D.C., Mike Grella, the company’s director of economic development public policy, slammed the “leaker” behind the article. “Memo to the genius leaking info about Crystal City, VA as #HQ2 selection. You’re not doing Crystal City, VA any favors. And stop treating the NDA you signed like a used napkin,” Grella tweeted. The company has yet to comment on the report, and it wasn’t immediately clear if Grella’s comments were a confirmation of Crystal City being selected. The Washington Post noted in its report that the company may also be having similar discussions with other finalists, and The Wall Street Journal on Sunday reported that Amazon is also engaged in “late-stage discussions” with Dallas and New York City.
