The Clintons have long ties to de Blasio. The mayor-elect was a regional director at the Department of Housing and Urban Development during Bill Clinton’s presidency and served as campaign manager for Hillary’s successful Senate bid in 2000.

De Blasio said in a statement Saturday that he is "honored" the Clintons will be in attendance.

“Wednesday’s ceremony will be an event for every New Yorker from all five boroughs, and Chirlane and I couldn’t be more excited to have President Clinton and Secretary Clinton stand with us.” 

Many political observers see de Blasio as leading a liberal resurgence in the Democratic Party, a trend that Hillary — seen as more centrist — might want to connect herself to ahead of a presidential run.

In October, she headlined a fundraiser for de Blasio's mayoral campaign that raised more than $1 million.

In an hour-long ceremony, Clinton will swear in the 109th mayor of New York with a Bible once owned by former President Franklin Delano Roosevelt.
