The Trump administration has aggressively rolled back efforts across the federal government to combat human trafficking, a Guardian investigation has found.

The sweeping retreat threatens to negate decades of progress in the drive to prevent sexual slavery, forced labor and child sexual exploitation, according to legal experts, former government officials and anti-trafficking advocates. They say the administration’s moves are impeding efforts to prosecute perpetrators and protect survivors in the United States and around the world.

“It’s been a widespread and multi-pronged attack on survivors that leaves all of us less safe and leaves survivors with few options,” said Jean Bruggeman, executive director of Freedom Network USA, a national coalition of service providers, researchers and trafficking survivors.
