The site is largely known for promoting and facilitating human trafficking and illegal transactions.

Paxton made combating human trafficking a top priority two years ago when he launched his office's human trafficking and transnationally organized crime unit.

Paxton said, "Backpage was involved in 73% of child trafficking cases reported to the National Center for Missing and Exploited Children. By taking down Backpage we are undoubtedly saving lives and sparing many others from the horrors of human trafficking."

The shutdown comes after the CEO of Backpage was arrested in Houston back in October after evidence was uncovered at the company's headquarters in Dallas.
