NEW ORLEANS (AP) The first day of testimony for a former BP executive's trial in connection with the 2010 oil spill ended with the judge telling jurors they probably will begin deliberating Friday in the case against David Rainey.

In opening arguments Tuesday, a prosecutor told jurors that Rainey manipulated early estimates of the amount of oil spewing into the Gulf of Mexico to match low government estimates, and then lied about it to federal agents.

Defense attorneys said Rainey's estimates were the best he could do in the week after the Deepwater Horizon oil rig exploded. They said he did not have any reason to lie when questioned about his calculations a year later.

The trial originally was expected to take three weeks. Judge Kurt Engelhardt didn't explain the new time estimate to jurors.
