Joe Biden has held many positions in his career as a U.S. senator, two-time presidential candidate, and vice president. But this weekend he will assume a new role: Father of the bride.

The vice president is spending the week at his home in Wilmington, Del., as he prepares to walk his only daughter, Ashley, down the aisle there this Saturday.

"The vice president's daughter is getting married this weekend. And the vice president is hosting the reception at his house," White House Press Secretary Jay Carney told reporters today. "As any father would, he takes this matter very seriously and looks forward to it with great happiness for his daughter and his future son-in-law."

Carney did not, however, have any details on the dress.

Ashley is set to wed Dr. Howard Krein, a Philadelphia ear, nose and throat doctor. News of Ashley's engagement leaked last October after her gaffe-prone father reportedly referred to Krein in public as his "future son-in-law."

The couple had been dating for roughly a year when the physician popped the question last September.

Ashley, 30, is the youngest of the vice president's children and his only child with wife, Dr. Jill Biden. The vice president has two sons, Beau and Hunter, from his marriage to Neilia Hunter Biden, who died in a car accident in 1972 along with their 13-month-old daughter, Naomi.
