AP condemns US telephone record seizure

The Associated Press has described the US government's secret seizure of its journalists' telephone records as a "massive and unprecedented intrusion".

The justice department has provided no explanation for the seizure but officials have previously said the District of Columbia prosecutor was conducting a criminal investigation into information contained in an AP story last year.

Published in May 2012, the article was about a CIA operation in Yemen that foiled an al-Qaeda plot to blow up a US-bound airplane.

David Willis reports that the Obama administration has brought more cases against people suspected of leaking information than any other.
