I really don't understand why Natsios explicitly excluded family planning programming from those programs he called "life-saving" in his statements today, especially when he's made statements like these in the past. www.congress.gov/116/meeting/...

I feel a strong moral obligation to speak up about my story, since I was gifted with the MIRACLE of pro-bono representation by the amazing Dori Hanswirth & her awesome team at Arnold & Porter. Others in more precarious situations facing SLAPPs feel less safe speaking out. It keeps me up at night!
