Bill Clinton will swear in Bill de Blasio at the inauguration Wednesday of New York City's 109th mayor, and Hillary Clinton will also attend the ceremony.
De Blasio will take the oath of office on the steps of City Hall from the 42nd president, using a Bible once owned by former President Franklin Delano Roosevelt, the mayor-elect's transition office said Saturday.
"Chirlane and I couldn't be more excited to have President Clinton and Secretary Clinton stand with us," de Blasio said in a written statement. referring to his wife, Chirlane McCray.
The noon swearing-in ceremony is a formality, because the official turnover to de Blasio from Michael Bloomberg takes place at midnight on Dec. 31.
De Blasio's office hasn't yet said who would be administering the oath at midnight. Bloomberg took his, on New Year's Eve 2001, from the then-outgoing mayor, Rudy Giuliani, but was sworn in at a public ceremony by the state's top judge at the time, Judith Kaye.
De Blasio, currently the city's public advocate, had worked for both Clintons -- for Bill as a regional director of the U.S. Department of Housing and Urban Development, and for Hillary as the campaign manager of her 2000 race for the Senate.
The Bible to be used is on loan from the FDR presidential library and museum in upstate Hyde Park.
De Blasio's inauguration is the first in recent memory to be open to the public. But the 1,000 public tickets, made available last week on the Internet, were gone within hours. Overall, more than 5,000 are to attend the outdoor ceremony.
Wednesday's forecast calls for temperatures to hit a high of 30 degrees -- and a low of 12.
After the ceremony, de Blasio and his wife are scheduled to greet the public, with an open house on Jan. 5 at the Gracie Mansion mayoral residence.
