WILMINGTON, Del. (AP) — President Barack Obama and Bill and Hillary Rodham Clinton are among the dignitaries set to join Vice President Joe Biden at the funeral of his eldest son today.

Former Delaware Attorney General Beau Biden died of brain cancer a week ago at age 46.

Obama and Beau Biden's siblings, Hunter and Ashley, are among those scheduled to speak at St. Anthony of Padua Roman Catholic Church in Wilmington, Delaware, as is Gen. Ray Odierno, the former top U.S. commander in Iraq, where Beau Biden once served.

Although the church typically seats less than 1,000 people, portable seats are being added to accommodate what officials expect to be a massive showing by politicians and Delaware residents alike.
