The Port of New Orleans filed a lawsuit against the owners of an asphalt tanker the same day it crashed into a river cruise boat on the Mississippi with 180 people on board.

According to court documents, the lawsuit was filed late Friday in federal court.

What we know: It's the first of what will likely be numerous lawsuits filed after video from the scene showed a much larger Atlantic Asphalt tanker hit the American Heritage cruise boat while it was docked.
