A writer who has known Donald Trump for three decades believes the US president will resign from office before the end of the year.

Tony Schwartz, the ghostwriter of Trump's 1987 Art of the Deal memoir, took to Twitter on Thursday to make his prediction about Trump's political future.

“The circle is closing at blinding speed. Trump is going to resign and declare victory before Mueller and Congress leave him no choice," Tony Schwartz said Thursday.

"Trump must be isolated. Resistance every day. The end is near but must keep pressure high," he added.

"Trump's presidency is effectively over. Would be amazed if he survives till end of the year. More likely resigns by fall, if not sooner,” he continued.

US Special Counsel Robert Mueller along with several congressional committees are investigating whether the Russian government coordinated with Trump's associates during the 2016 campaign and transition, accusations both Trump and Moscow have denied.

Mueller has also impaneled a grand jury, meaning he is allowed to subpoena officials and get sworn testimony which may lead to criminal indictments.

Mueller is reportedly seeking to interview current and former administration officials as part of his investigation into Russia’s alleged interference in the 2016 presidential election.

Trump has condemned the investigation into possible collusion between his election campaign and Russia as the “greatest witch hunt” in the US history.

Schwartz made a similar prediction in May. “There is no right and wrong for Trump. There’s winning and losing. And that’s very different from right and wrong. Right now he’s in pure terror that he is going to lose," Schwartz said. "And by the way, he is going to lose.”

Mueller was appointed by Deputy Attorney General Rod Rosenstein to lead the probe which will also look into “related matters.” 

He was at the helm of the Federal Bureau of Investigation for 12 years, between 2001 and 2013.
