Walmart is suing the US government in a pre-emptive strike in the battle over its responsibility in the opioid abuse crisis.

The government is expected to take civil action against the world’s largest retailer, seeking big financial penalties, for the role its pharmacies may have played in the crisis by filling opioid prescriptions.
