The event will be held in the home of Steve Elmendorf, founder of Elmendorf Ryan, a well-connected lobbying firm.

In an email to The Hill, Elmendorf confirmed that O'Malley is expected to attend the fundraiser and that the event will be held in his home.
The Human Rights Campaign, the prominent gay-rights group, is also listed on the invitation.
Tickets to the fundraiser are going for $250 to receive “bronze” status, $500 for “silver” and $1,000 for “gold,” according to the invitation.
O’Malley has supported legalizing same-sex marriage in his state. Earlier this year, the Maryland governor signed a bill that would allow same-sex couples to marry in 2013.
Same-sex marriage opponents, however, gathered enough signatures to have a referendum on the law this November, when voters will decide whether or not to overturn the law.
O’Malley is expected to attend another fundraiser for same-sex marriage later next month.
The governor is slated to attend a Monday Night Football party on Oct. 8 with Baltimore Ravens linebacker Brendon Ayanbadejo, who has attracted headlines for his support of same-sex marriage, to raise money to support the cause in Maryland.
“This November, we have the opportunity to be the first state ever to defend marriage equality and fairness at the ballot box. With supporters like you and Brendon, I know we will. But we have to fight for it,” O’Malley said in a fundraising email for the event.
