From Salon:

On Monday, “Citizenfour” director Laura Poitras filed a lawsuit against the U.S. government seeking to find out why she was searched, questioned and detained at U.S. borders and foreign airports more than fifty times between 2006 and 2012. Poitras, who won an Oscar this year for her documentary “Citizenfour,” about NSA whistleblower Edward Snowden, is filling a FOIA suit against the Department of Justice, the Department of Homeland Security and the Office of the Director of National Intelligence demanding that they release records pertaining to the “Kafkaesque harassment” she received at U.S. borders over a six year period.
