'Let's go, Brandon': Caller pranks Biden at White House event

A caller has pranked US President Joe Biden by dropping an anti-Biden taunt into their chat during a White House Christmas event.

Mr Biden and First Lady Jill Biden were hosting the festive call for families when a father told the president: "Let's go, Brandon."

Apparently unaware of the gibe, Mr Biden said he agreed.

The term, which has become a rallying cry for many conservatives, is code for a profane insult directed at Mr Biden.

The first couple were speaking virtually with children for a White House custom, tracking the journey of Santa's sleigh via the North American Aerospace Defence Command.
