Who Is Jofi Joseph? All About @NatSecWonk And The Tweets That Got White House Staffer Fired

Jofi Joseph has been outed as the man behind @NatSecWonk, the anonymous and biting Twitter account that took aim both at Obama administration officials and Republicans. Making matters worse for the president, Joseph was part of his national security staff. He has since been fired.

The Twitter account is now defunct. Now that Joseph has been unmasked, here are five things to know about the @NatSecWonk owner who has been thrust into the media spotlight:

1) He was running the Twitter account for more than two years

Joseph had been tweeting on @NatSecWonk since February 2011. The account’s targets of ridicule have included everyone from Obama administration staffers and U.S. Secretary of State John Kerry to Sarah Palin and Mitt Romney’s 2012 presidential campaign team. One unanswered question, in light of the administration’s embarrassing NSA scandals, is whether investigators suspected an administration official was behind the account when it began the probe.

2) The tweets that got him in trouble

While @NatSecWonk is not active anymore, The Daily Beast saved a few of Joseph’s most recent tweets. They include:

“I'm a fan of Obama, but his continuing reliance and dependence upon a vacuous cipher like Valerie Jarrett concerns me.” This posting certainly didn’t sit well with Obama – Jarrett is a close aide and friend of the president.

“Was Huma Abedin wearing beer goggles the night she met Anthony Wiener? Almost as bad a pairing as Samantha Powers and Cass Sunstein,” he wrote. The tweet bashed four people – former U.S. Secretary of State Hillary Clinton’s chief of staff, her husband and former U.S. congressman, and two Obama aides, both prominent authors.

3) Joseph was on Obama’s national security staff as the director for nonproliferation

He got the job in August 2011 – seven months after he started @NatSecWonk – and was fired after an investigation determined he was the man behind @NatSecWonk.

4) His previous background

Joseph’s work for Obama wasn’t his first D.C. rodeo. Before joining the Obama administration, Joseph was a staffer on the Senate Foreign Relations Committee from 2001 to 2004. The committee was chaired by then-Sen. Joe Biden, who relied on Joseph on issues ranging from arms control to nonproliferation and U.S. military assistance. In 2007, Joseph was adviser to U.S. Sen. Bob Casey, D-Pa., for foreign policy, national security and homeland defense issues.

5) Education

Joseph earned his degree in foreign service from Georgetown University and a master’s degree in public administration from Princeton University in 1999.
