Sky News host James Morrow says one of US Vice President Kamala Harris' recent speeches was a "load of nonsense".

At the ASEAN summit, Ms Harris used the phrase 'work together' multiple times while speaking about the climate crisis.

"Literally, it is a bunch of post-it notes taken off the wall at a corporate retreat where they're trying to figure out the mission statement for a company that nobody knows what they do," Mr Morrow told Sky News host Rita Panahi.

"It just doesn't make any sense."
