Moore: 'US investigation timing is insane'

Filmmaker Michael Moore is baffled by the timing of a US federal investigation into his trip to Cuba for new movie Sicko, because the government knew about his plans to travel to the Caribbean island last year.

Earlier this month, Moore received a letter from the US Treasury Department's Office Of Foreign Assets Control, notifying him that it was conducting a civil investigation for possible violations of the trade embargo restricting travel to Cuba.
