John Hawkins of Right Wing News talked to Andrea Clark’s sister (I blogged about this here):

I spoke to Andrea’s sister, Melanie Childers, again today to get an update on what’s happening. To begin with, she said that a lot of pro-life people have been calling the hospital and she thinks it’s having a real effect on them. She said that she hopes people keep it up. (The contact page for St. Luke’s Episcopal Hospital is here. If you call, no matter how upset you may be, make sure to be polite).

Read more here. And you should check his site throughout the week to see if there are any updates.
You can find contact information here.
Updated to add: The hospital may be paying to move Andrea Clark to a hospital in Illinois according to Wizbang.
