>>> back now with a problem more anded more offices and workplaces are having to confront in this age of anonymity online. the the worker who bad mouths co-workers on social media without anybody being able to figure out their identity. the office in this case tonight happens to be inside the white house . tonight a top national security official is out of a job after being publically exposed. our report tonight from our political director and chief white house correspondent chuck todd .
>> reporter: at the white house jofi joseph was known as a smart, if unremarkable national security policy wonk . the anonymous twitter account he created was remarkable and featured tweets such as this one about one of the president's closest advisers. i'm a fan of obama, but his continuing reliance and dependence upon a vac wous cipher like valerie jarrett concerns me. it made his alter ego an internet sensation and promised dirt. he says what everyone else only thinks. i'm abrasive and bring the snark. including was huma abedin wearing beer goggles the night she met anthony weiner ? and more people should be asking why john kerry installed two former aides with zero foreign policy experience into top posts at state. they zeroed in on joseph , gave him misinformation to entrap him. then the white house counsel 's office got involved and they dismissed him. he denied requests to comment but e-mailed this statement apologizing and taking full responsibility writing, what started as an intended parody account developed into a series of inappropriate and mean-spirited comments.
>> these issues are shockingly common in the work place.
