After 40 years of marriage, Al Gore and his wife Tipper are separating.

Details (as expected) are light, but apparently the site Politico obtained an e-mail from the Gores confirming the split. From the site:

In an “Email from Al and Tipper Gore,” the couple said: “We are announcing today that after a great deal of thought and discussion, we have decided to separate.

“This is very much a mutual and mutually supportive decision that we have made together following a process of long and careful consideration. We ask for respect for our privacy and that of our family, and we do not intend to comment further.”

The information in the e-mail was confirmed by Gore's press official, Kalee Kreider.
