WASHINGTON (AP) — Emails by Attorney General Eric Holder from early 2011 express the need to get to the bottom of allegations that a risky law enforcement tactic had been used in Operation Fast and Furious.

In the early days of the controversy, two of Holder’s e-mails and one by Deputy Attorney General James Cole expressed growing concern that something might have gone wrong in the flawed federal gun-smuggling probe.

In one e-mail, Holder tells aides, quote: “We need answers on this.”

The full contents of the e-mails were described to The Associated Press by two people who have seen them.
