Among the topics on which Trump offered scant details were how he would reduce taxes and cut back on business regulations, according to two other people in the room who spoke to CNBC.

The same CEOs who were struck by Trump’s lack of focus “walked into the meeting being Trump supporter-ish or thinking that they might be leaning that direction,” Sorkin reported.

“These were people who I think might have been actually predisposed to [Trump but] actually walked out of the room less predisposed” to him, Sorkin said.

“At one point, he discussed his plan to bring the corporate tax rate down from 21% to 20% … and was asked about why he had chosen 20%,” Sorkin said Friday on MSNBC’s “Morning Joe.” “And he said, ‘Well, it’s a round number.’”

“That unto itself had a number of CEOs shaking their heads,” Sorkin reported.
