Let's take a look at the tweeting newsroom behind Foreign Policy Magazine, a bimonthly American magazine founded in 1970 originally as an academic quarterly. Their most highly followed journalist is David Kenner, Middle East Editor, followed by Colum Lynch, UN Reporter; Dan Lamothe, National Security Reporter; Isaac Stone Fish, Asia Editor; John Hudson, Staff Writer; and Shane Harris, Senior Writer.
Meanwhile, their most active journo on Twitter this morning is Yochi Dreazen, Deputy Editor, News, while their highest trending article at the moment is a piece by Hanna Kozlowska titled "Russia Sanctions Fail to Soothe Poland’s Frayed Nerves." Definitely worth a read at some point today.
