Trafficking Victims Protection Act (TVPA): This federal law was first passed in 2000 and has been reauthorized several times since then. It provides a comprehensive approach to combating human trafficking, including provisions for prevention, protection, and prosecution. The TVPA also established the Office to Monitor and Combat Trafficking in Persons within the US State Department.

Stop Enabling Sex Traffickers Act (SESTA) and Allow States and Victims to Fight Online Sex Trafficking Act (FOSTA): These two bills were passed in 2018 to address online sex trafficking. They hold websites accountable for facilitating sex trafficking and allow victims of trafficking to sue websites that knowingly facilitated their victimization.

Child Protection Improvements Act: This law requires background checks for individuals who work with children or vulnerable populations, such as those who work in schools, daycares, or after-school programs.

Runaway and Homeless Youth and Trafficking Prevention Act: This bill provides funding for programs and services that support runaway and homeless youth, including those who are at risk of trafficking or who have experienced trafficking.

Strengthening Child Welfare Response to Trafficking Act: This law seeks to improve the child welfare system's response to child trafficking by providing funding for training and resources for child welfare professionals and requiring data collection on child trafficking within the system.

Overall, these laws and bills aim to prevent, identify, and respond to child trafficking in the United States. However, it is important to note that more work needs to be done to address this issue, and individuals can play a role in combatting child trafficking by staying informed, supporting organizations that work to end trafficking, and advocating for stronger laws and policies to protect vulnerable populations.
