The trial is winding down for a former BP drilling engineer.
Kurt Mix is charged with deleting text messages about the company's response to its massive 2010 oil spill in the Gulf of Mexico.
Jurors are expected to hear closing arguments today in his trial on two counts of obstruction of justice.
Each count carries a maximum sentence of 20 years in prison and a $250,000 fine.
Mix pleaded not guilty but did not testify.
His attorney says Mix deleted the text for quote "the most innocent of reasons" and didn't hide anything from the Grand Jury.
