NEW ORLEANS (AP) — Attorneys for one of the men facing criminal charges in connection with the 2010 Gulf oil spill are hashing out a variety of issues ahead of a March trial.

The defendant is former BP executive David Rainey, who has pleaded not guilty to charges that he obstructed a congressional investigation into the spill.

A Wednesday hearing deals with a variety of issues including whether certain evidence about the flow rate from BP's ill-fated Macondo well should be excluded from trial; and whether part of the indictment should be dismissed.
