Former White House chief of staff Mick Mulvaney joined Sky News host Andrew Bolt to discuss the Republic National Convention in Milwaukee on Monday where former US president Donald Trump made his first appearance since the assassination attempt.

Mr Trump appeared with a bandage around his ear where he was injured by a flying bullet after a shooter at his rally over the weekend fired multiple shots in his direction.

Thousands of Republican delegates from across the United States had arrived at the Fiserv Forum in Milwaukee, Wisconsin, on Monday (local time).
