Despite his alleged Catholic faith, Mayor-elect Vincent Gray voted to legalize gay "marriage" in the District of Columbia. However, the Washington Post informs us that Cardinal Wuerl is scheduled to deliver the invocation and benediction at Gray's mayoral inauguration on January 2, 2011.
The same Post article also informs us that Gray attends Mass regularly. I wonder if he attends Confession regularly? Unless he's publically repudiated his support of gay marriage, I would hope his parish priest obeys Canon 915 if Gray were to dare present himself for Holy Communion.
All inaugural events are slated to occur in the Walter Washington Convention Center. More details and a map are at this link.
