‘Serious player’: Donald Trump returns to Instagram

Former US President Donald Trump's recent return to Instagram has made him a "serious player" in the United States again, according to Peter McGauran, a former advisor to John Howard.

McGauran's comments come amid a surge of support for Trump from Americans following his recent appearance in court.

“Because of the treatment of the courts about him,” Mr McGauran told Sky News Australia.

“There’s always an enquiry, there’s always a prosecution against Trump – and nothing against any of the Democrat figures.”
