For some, Donald Trump’s promise to run the country like he ran the Trump Organization was always more of a threat than a selling point. “God help us,” fellow New Yorker Michael Bloomberg said last year, during the Democratic National Convention, as he enumerated Trump’s many business failures. Clearly, though, many were taken in by the prospect. Now, six months into the Trump presidency, we‘ve gotten a better look at how the self-proclaimed billionaire’s management skills rate: so poorly that M.B.A programs across the country are presumably using the Trump White House as a case study in how not to run a business. The handful of actual business titans who signed up to serve as White House advisers seem to have woken up to this reality, too. According to a new report from Bloomberg, Trump’s heralded C.E.O. committees, which were supposed to come up with bold new ideas for turning around U.S.A, Inc., have largely fallen silent.

In fact, there’s been little activity for the strategy and policy forum and the manufacturing group, according to people familiar with the matter who asked not to be identified. After initial meetings early in Trump’s presidency—which the White House promoted with great fanfare—his administration hasn’t convened the groups for months or set firm dates for future meetings, according to the people. As turmoil has engulfed Washington, some prominent business leaders, including several of these informal advisers, have begun to distance themselves from the president. Tesla Inc. C.E.O. Elon Musk and Walt Disney Co. C.E.O. Bob Iger went even further, quitting in June after Trump withdrew from the Paris climate accord. Former Uber Technologies Inc. C.E.O. Travis Kalanick quit in February, following Trump’s controversial executive order on immigration.

According to reporters Matthew Townsend, Shannon Pettypiece, and Joe Deaux, the manufacturing group hasn’t met in five months, while the strategy and policy forum, headed by Blackstone chief Stephen Schwarzman, last met on April 11 (Trump previously said the group would meet monthly). According to the White House, though, the lack of activity is not indicative of an administration that has lost the support of the corporate world, but rather one that is so successful that it’s already got all the bold new ideas it needs. “We spent the first few months of the administration meeting with hundreds of C.E.O.s to listen and are now putting those learnings into action,” a White House official told Bloomberg. “The roundtables and council meetings have directly impacted the administration’s policies in areas like workforce development, deregulation, and tax reform. We will continue to meet with and engage with C.E.O.s across all relevant policies.”
