US President Joe Biden has been mocked online after appearing to make a series of gaffes during the DDay anniversary in Normandy on Thursday.

During the event, Biden seemed unsure whether to stand or sit, awkwardly halfsquatting as he searched for a chair.

First Lady Jill Biden, with her hand over her mouth, appeared to be mouthing words of guidance to him.

Jill Biden later led him away while French President Emmanuel Macron stayed to greet veterans, some over 100 years old.

"The vets look more with it than Biden," one user wrote on X.
