Former US President George Bush dances at a funeral

Former US President George W Bush has faced a barrage of criticism online after dancing during a hymn at a memorial service for five murdered police officers.

Bush raised eyebrows with his dance moves at a service to remember the five police officers shot dead by snipers at the Dallas Black Lives Matter protest.

Holding hands with his wife, Laura, and Michelle Obama, Bush is seen smiling and dancing while the choir sang "Battle Hymn of the Republic" at the event in the Texas city.

His awkward moves left many on social media cringing and questioning whether his behaviour was appropriate given the somber, emotional occasion.

One Twitter user, Roger Cullins, said: "I usually like Bush - but why in the world was he dancing and being goofy during last song? I was cringing."

Kelly Byrd tweeted: "George Bush dancing to ‘Glory Glory Hallelujah’ at the #DallasMemorial while smirking makes my heart hurt."

The video shows Michelle and Barrack Obama looking at the former President and appearing confused.

Steve Silberman said: "The look on Michelle Obama's face as Bush starts rocking out at a funeral is everything."
