Fire and Fury: Inside the Trump White House by Michael Wolff:
While he wanted a job with the Trump administration, the Mooch specifically wanted one of the jobs that would give him a tax break on the sale of his business. A federal program provides for deferred payment of capital gains in the event of a sale of property to meet ethical requirements. Scaramucci needed a job that would get him a “certificate of divestiture,” which is what an envious Scaramucci knew Gary Cohn had received for the sale of his Goldman stock.
A week before the inaugural he was finally offered such a job: director of the White House Office of Public Engagement and Intergovernmental Affairs. He would be the president’s representative and cheerleader before Trump-partial interest groups.
But the White House ethics office balked—the sale of his business would take months to complete and he would be directly negotiating with an entity that was at least in part controlled by the Chinese government. And because Scaramucci had little support from anybody else, he was effectively blocked. It was, a resentful Scaramucci noted, one of the few instances in the Trump government when someone’s business conflicts interfered with a White House appointment.
