Jofi Joseph, a director in the non-proliferation section of the National Security Staff at the White House, has been surreptitiously tweeting under the moniker @natsecwonk, a Twitter feed famous inside Washington policy circles since it began in February, 2011 until it was shut down last week. Two administration officials confirmed that the mystery tweeter was Joseph, who has also worked at the State Department and on Capitol Hill for Senators Bob Casey (D-PA) and Joe Biden. Until recently, he was part of the administration's team working on negotiations with Iran.
On the other hand, he also called Jennifer Rubin and Sarah Palin nuts. So there's that.During his time tweeting under the @natsecwonk name, Joseph openly criticized the policies of his White House bosses and often insulted their intellect and appearance. At different times, he insulted or criticized several top White House and State Department officials, including former National Security Advisor Tom Donilon, Deputy National Security Advisor Ben Rhodes, Secretary of State John Kerry, and many many others.
