State treasurer Rob McCord has joined a lawsuit challenging Pennsylvania's ban on same-sex marriage.
McCord, a Democratic candidate for governor, has petitioned a federal court for permission to submit a friend-of-the-court brief in the pending marital rights case.
In his filing, McCord argues Pennsylvania's law defining marriage as the union of one man and woman should be overturned as unconstitutional.
He said as treasurer, he must enforce and comply with a discriminatory law that sometimes denies retirement and other benefits to same-sex spouses after the death of a partner.
McCord is the first state elected official to formally challenge Pennsylvania's
marriage law in a legal proceeding.
