Hi, a lot of this is simply be because he was president during those years.

FOSTA had near universal support in Congress, it passed the Senate 97-2.

January has been Human Trafficking Prevention month since 2010.

When you say "Trump gave $100 million"...this was through a Department of Justice Program created by Congress in 1988 that covers various types of crimes.

The Office for Victims of Crime (OVC) was established in 1988 through an amendment to the 1984 Victims of Crime Act to oversee diverse programs that benefit victims of crime.

Victims of Human Trafficking have been covered since the Clinton Administration.

Under the Trafficking Victims Protection Act of 2000 and subsequent reauthorizations, OVC receives specially designated government funds, independent of appropriations from the Fund, to support victim service organizations to provide trauma-informed, culturally appropriate services for survivors of human trafficking.

Last year the same amount was granted as 2020.

To say Trump "gave" this is to misunderstand this. https://ovc.ojp.gov/program/human-trafficking/grants-funding
