CSpan is covering it, not sure about others.......
EWTN will also cover the March for Life. In the past the alphabet channels had nothing or very little. I remember WaPo, even before it became the billionaire blog, would have 2 pictures, one showing a small group of pro-life marchers and one of pro-choice demonstators. One showed about 15 of 200,000; the second was the total there. I have not attended for the past decade, ever since I moved away from a DC suburb so I am really looking forward to being part of it again.
