One Nation senator unfurls revolutionary flag to celebrate Donald Trump victory

One Nation senator Malcolm Roberts has celebrated Donald Trump's election victory by unfurling a flag linked to the Tea Party movement on the steps of parliament.

Senator Roberts held the Gadsden Flag, an American Revolutionary War-era flag associated with the conservative Tea Party movement, which is emblazoned with a coiled rattle snake and the words "don't tread on me".

The senator lauded Mr Trump and his US election victory and said the flag symbolised government serving the people, "not the people serving the government".

He criticised Australia's major political parties for not embracing a Mr Trump presidency, saying he hoped to meet the US president-elect.

He has also claimed to have already received invitations to "connect" to the Trump presidency.

"He's dismantling the establishment and what we have is only One Nation, Pauline Hanson's One Nation, capable of dealing with Donald Trump's presidency," Senator Roberts said.
