What action does the USA PATRIOT Act allow the US government to take regarding financial...

Section 319(b) of the USA PATRIOT Act authorizes the U.S. government to subpoena records from any foreign bank that maintains a correspondent account in the U.S., regardless of whether the foreign bank has a physical presence in the U.S. or not. The subpoena may request any records relating to the correspondent account or any account at the foreign bank, including records maintained outside the U.S. If the foreign bank fails to comply with the subpoena, the U.S. government may direct any U.S. financial institution to terminate its correspondent relationship with the foreign bank and impose civil penalties.
