Tammy Baldwin and her partner Lauren Azar split

Rep. Tammy Baldwin (D-Wis.) and Wisconsin Public Service Commissioner Lauren Azar are ending their 15-year domestic partnership, according to a statement from Baldwin’s office.

In 2009, Baldwin and Azar were one of the first couples to register their same-sex partnership with the state’s domestic partnership registry. The statement said that domestic partnership will be legally terminated.

Baldwin was elected to Congress in 1998, becoming the first openly gay woman in the legislative branch.

According to a spokeswoman, “neither Tammy nor Lauren will have any further public comment on this very private matter.”
