Gov. Sam Brownback will speak on “Ending Human Trafficking” at 6 p.m. Thursday in the Kansas University Union Ballroom.

When serving in the U.S. Senate, Brownback co-sponsored the Trafficking Victims Protection Act of 2000, which serves to protect victims of human trafficking and to punish offenders.

Federal officials have said that human trafficking — a modern form of slavery involving women, men and children — is tied with the illegal arms industry as the world’s second-largest criminal enterprise.

Brownback’s talk is sponsored by the Emily Taylor Women’s Resource Center.
