Your very last line was interesting.
“Trump offered to list Aramco, the Saudi oil company, on the NYSE.”
That’s good if it’s the right time to do such.
But I didn’t know a president could make facilitate such an addition to the NYSE. I thought that would come from someone like Yellen. Learn something new everyday.
It's not in the official job description, but through the secretary of commerce or treasury, he could almost certainly block a foreign company from being listed. The Saudis probably asked for the company to be listed during his visit in April, and President Trump asked for help removing deep state funding coming from SA.
