U.S. President Barack Obama is expected to implement several changes to the National Security Agency's controversial surveillance tactics in a speech on Friday.
The speech comes in response to a global debate on government surveillance sparked by a series of reports revealing far-reaching, secret NSA spying programs. Former NSA contractor Edward Snowden, who leaked a trove of secret documents to journalists early last year, has been the media's primary source of information for these reports.
A number of reports throughout the week speculated on the specific reforms that Obama will discuss in the speech. Mainly, he is expected to address the NSA's controversial bulk collection and storage of telephone metadata.
