(CNN) —  

President Donald Trump’s third national security adviser, John Bolton, tendered his resignation on Tuesday, marking the latest departure from an administration fraught with turnover.

Though the role of national security adviser is not Cabinet-level, there are still six Cabinet-level positions that are open within the Trump administration: chief of staff, homeland security secretary, labor secretary, Office of Management and Budget director (Mick Mulvaney technically still holds this position but there is an acting director), director of national intelligence and Small Business Administration administrator.

Here is President Donald Trump’s current Cabinet:
