George W. Bush caught passing candy to Michelle Obama at McCain memorial service

WASHINGTON - A moment between former first families has gone viral -- as former President George W. Bush is caught passing a piece of candy to former First Lady Michelle Obama during the memorial service for late Sen. John McCain on Saturday.

As former Sen. Joe Lieberman paid tribute to his friend and colleague, the camera turned to the audience as Lieberman made a joke about McCain, catching the brief moment between the former president and former First Lady.

Lieberman was speaking on his relationship with McCain and their religious differences, as McCain would joke about Jewish traditions Lieberman followed.

George W. Bush and Michelle Obama have been observed for their seemingly-close bond, seen together at the dedication of the National Museum of African American History and Culture in 2016.

With partisan politics continuing to create division in the current political climate, the seemingly unlikely friendship between Bush, a Republican, and Obama, a Democrat, has sparked conversation on social media.

Republican Sen. Jeff Flake from Arizona tweeted a photo of the moment: "Decency wins."
