Johnson-Harrell won two thirds of the vote in a special election for the 190th district. She ran against three other candidates, with just a four week long campaign.
"We touched approximately 10,000 people five times in four weeks," Johnson-Harrell said.
Johnson-Harrell was most recently the head of victim services for the Philadelphia District Attorney's office before taking a leave of absence to run. The gun control advocate and University of Pennsylvania graduate founded the CHARLES Foundation 8 years ago, after her son Charles Johnson was gunned down in a case of mistaken identity.
"To fight for our young people on both sides of the gun, also to empower our communities," she said about the foundation.
