Vice President Biden is scrapping an appearance at the Human Rights Campaign's annual dinner due to the government shutdown, his office said Thursday.
Biden had originally been slated to give the keynote address at the gay rights group's Oct. 5 dinner.
The vice president has become a popular figure in the gay rights community following his decision to express support for gay marriage in May 2012.
At the time, President Obama has not yet announced his support for same-sex marriage. When the president eventually voiced his support for gay marriage, he acknowledged that Biden's statements had forced the issue for him.
Human Rights Campaign has sold out the dinner, which is expected to draw 3,400 guests.
