Nearly all of the United States has failed to properly address the issue of human trafficking, according to a new report from Shared Hope International.

The human rights advocacy group gave 41 states a "D" grade or lower in adopting laws and penalties to lower modern day slavery and sex trade.

Researchers analyzed how states care for trafficking victims and how forcefully they prosecute traffickers and buyers.

They found that four states -- West Virginia, Virginia, Maine and Wyoming -- don't have human trafficking laws at all.

And only four states -- Illinois, Minnesota, New York and Washington -- have a adequate services and shelter care for child victims.

For more on the issue of human trafficking in the United States, CBN News spoke with former congresswoman and Shared Hope International founder Linda Smith.
