ATHENS, Greece (AP) — U.S. Attorney General Eric Holder says the Obama administration will seek to introduce legislation granting European citizens the same privacy protection rights available to US citizens, when their data is being transferred from the European Union to the U.S. for law enforcement purposes.

The U.S. and EU have been negotiating for more than four years on the protection of personal data. Holder made the announcement Wednesday after an EU-U.S. Justice and Home Affairs ministerial meeting in Athens. Greece currently holds the six-month rotating EU presidency.
