Margie Winters and her wife, Andrea Vettori, have been hoping for months to speak with Pope Francis during his visit to America. On Wednesday, the couple will take a big step toward that goal in a high-profile venue. Winters, who was fired from Waldron Mercy Academy in Merion in late June after two parents of students complained about her same-sex marriage, has been invited with Vettori to the White House for Wednesday’s arrival ceremony for the bishop of Rome and leader of their faith. Human Rights Campaign, which calls itself the nation’s largest LGBT civil rights organization, confirmed Monday that it had secured tickets from the White House for Winters and Vettori to attend the event, which is not open to the public. The group on Monday featured Winters and Vettori on its website in a video, telling the story of their marriage, Winters’ firing, and Vettori’s letter to the pope pleading for his intervention. The couple, already planning on attending a full week of papal events in Washington and Philadelphia, were giddy with the news Monday night.
