It was a bittersweet celebration Wednesday for a Chicago mother who fought online sex trafficking.
Desiree Robinson was just 16 when she was found dead in a garage in Markham in 2016. She had been advertised as a prostitute on Backpage.com.
Her mother, Yvonne Ambrose, launched an all-out war against Backpage.com. She filed a lawsuit and testified in Washington.
On Wednesday, she was at the White House when President Trump signed a bill targeting websites that promote sex trafficking.
The new law weakens a shield some online companies used claiming they were merely third-parties and not responsible for content posted by sex traffickers.
