Facebook's week has taken another turn for the worse. The social network's general counsel Colin Stretch (above) has announced he's leaving the company by year's end, according to The Wall Street Journal. Stretch testified during the hearings in Washington, DC last November and has been with the company since 2010. He made the announcement via his Facebook page, saying that his departure was the result of logistics. A few years ago Stretch moved to Washington DC and apparently the differences in time zones and working with his team shaped the decision.
