President Donald Trump said his overhaul of the US tax code would bring back offshore profits providing pay rises worth $4000 to the typical American household, as he made his case to an audience of truckers in Pennsylvania on Wednesday night.

Mr Trump’s tax overhaul has taken on huge importance as other elements of his legislative agenda, such as repealing Obamacare, have become bogged down in Congress.

His tax plans have been criticised for offering tax breaks to the super-rich but Mr Trump insists his proposals would stimulate the economy, creating jobs and driving wages higher.

“It’s a middle class bill. That’s what we’re thinking of. That’s what I want,” he said.

In particular, the plan aims to attract US firms’ profits back from overseas for the benefit of American workers.
