WASHINGTON, As abortion advocates gather on the National Mall today to demand that Congress continue funneling hundreds of millions of tax dollars to Planned Parenthood, 40 Days for Life announced that its spring campaign is the largest and longest sustained demonstration outside Planned Parenthood offices in history. Planned Parenthood's abortion chain, which has performed more than 5 million abortions since 1970, receives $363.2 million in annual taxpayer funding.
