Tony Schwartz who happens to be the co- author of Donald Trump's book The Art of the Deal says he will resign in the coming weeks.
My Schwartz, who helped the president write his book back when he was just a businessman, made the prediction on Twitter.
He said: 'The circle is closing at blinding speed.
Trump is going to resign and declare victory before Mueller and congress leave him no choice.
'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.'
Schwartz has turned up the heat against Trump this week by constantly assassinating his character.
He said: 'Remember that every time Trump criticizes and demeans someone he is projecting his deep sense of inadequacy and self-hatred onto others.'
In a separate tweet which he's since deleted, he went after Trump's children and then apologized, adding: 'Yesterday I criticized Trump's children, and today deleted the tweet. I don't know them and I want to keep my comments focused on Trump.'
It has long been predicted that Trump would leave the White House before his colleagues got the chance to ever impeach him.
