I've posted on a couple of the C Street alumni before:
Our friends over at Roll Call, a respected Capital Hill newspaper, reported today that Dr. Tom Coburn (R-OK), has said that he will not testify about advice he may have given Sen. John Ensign (R-NV) on Sen. Ensign's affair. Sen. Coburn cites religious counseling and patient confidentiality protections.

You can read Roll Call's excellent article here.

One thing the article fails to mention is that Dr. Coburn is an OB/GYN. I’m curious as to what, exactly, he would be treating Sen. Ensign for?

Of course, once the DOJ started an investigation Sen. Coburn rolled on Sen. Ensign. Yep, nothing like 'family' values and loyalty to your friends is there, Tom?
