White House chaos now critical - Larry Jacobs

US President Donald Trump is playing down the resignation of his top economic advisor Gary Cohn after a heated disagreement over Mr Trump's steel and aluminium tariff plans. Mr Cohn's resignation sounded alarm bells in establishment circles in Washington and on Wall Street, where many viewed the former Goldman Sachs executive as a steadying influence on economic policy inside the Trump White House. The news sent stocks lower in early trading on Thursday. But Mr Trump says Mr Cohn will be easily replaced. The revolving door for White House staffers has been spinning rapidly since Mr Trump entered the Oval Office, but Larry Jacobs, the director of the Center for the Study of Politics and Governance at the University of Minnesota tells us the situation is reaching a critical point.
