Al Gore and his wife of 40 years, Tipper, are separating.
The couple wrote an email that found its way to Politico, saying, "We are announcing today that after a great deal of thought and discussion, we have decided to separate."
The email continues, "This is very much a mutual and mutually supportive decision that we have made together following a process of long and careful consideration."
The couple has 4 kids.
Roughly one year ago today -- the couple's daughter Kristin Gore filed for divorce from her husband Paul Cusack.
