It turns out that a White House mole, fired recently for snarky anonymous tweets about top Obama administration officials and its policies, is an Indian-American policy wonk.
Jofi Joseph, 40, who served as a non-proliferation expert on the National Security Council, was a key aide of President Barack Obama, whose administration has more Indian-Americans in key jobs than any other previous US administration.
Mr Joseph, who was said to be part of the team working on negotiations with Iran over its nuclear programme, was fired after it was discovered that he was the author of @NatSecWonk Twitter feed known for its snarky blasts about the Obama administration.
Under the cover of his alias, Mr Joseph, over two years, took aim at high-ranking administration officials and Republicans alike, slamming their intellect and criticising their appearance.
"I'm a fan of Obama, but his continuing reliance and dependence upon a vacuous cipher like Valerie Jarrett concerns me," he once reportedly tweeted of the president's senior adviser.
Summing up his colleagues, he tweeted another time, "'Has shitty staff.' #ObamaInThreeWords."
Again, it was Mr Joseph who reportedly supplied some of the ammunition to Republicans for torpedoing the nomination of Susan Rice, President Obama's first choice to succeed Hillary Clinton as secretary of state, over her handling of the government's response to the terrorist attack on the US consulate in Benghazi in Libya.
Mr Joseph did not spare Ms Rice either when President Obama appointed her National Security Adviser (NSA) a few months later.
"What's with the dominatrix-like black suit Susan Rice is wearing at this announcement?" he anonymously tweeted when Ms Rice was formally introduced as the new NSA at the White House on June 5.
Born in Germany where his parents, both Indians, were stationed in the early 1970s, Mr Joseph came to the US with his family when he was only six months old.
He graduated as the valedictorian of his Catholic high school in Muskegon, Michigan, where the family lived. He attended Georgetown University's School of Foreign Service, where he graduated in 1994.
A Democrat, Mr Joseph worked on the Senate Foreign Relations Committee advising then chairman Joseph Biden and later, as the principal foreign policy adviser to Senator Robert P. Casey Jr.
Jofi Joseph's wife, Carolyn Leddy, is a Republican staffer on the Foreign Relations Committee.
The Washington Post cited a former NSC official as saying "Joseph could be sarcastic and bitter, especially in regard to colleagues who were given higher-level positions that he did not think they were qualified for."
Time correspondent Michael Crowley who knew Joseph - fired "for his snarky and sometimes bilious tweets" - wrote in a recent piece that "in person he was nothing like his obnoxious Twitter persona."
"Over lunch or coffee he was less interested in trashing colleagues than in diving deep on Iranian centrifuge capacity or deterrence theory in a post-Soviet world," Mr Crowley wrote.
