Donald Trump said on Wednesday he may package a $1 trillion (£800bn) infrastructure plan with either healthcare or tax reform legislation as an incentive to get support from lawmakers, especially from Democrats.

The US president also said in an interview with the New York Times he may move up the unveiling of a plan to rebuild the country's deteriorating roads, bridges and tunnels, which had been expected later this year.

"I'm thinking about accelerating it. I'm thinking about putting it with another bill. Could be health care, could be something else. Could be tax reform," Mr Trump said.

The US president was stung by his first legislative push, a failed attempt to roll his predecessor's healthcare law, which ended in an embarrassing collapse in Congress two weeks ago.
