Do you think that Trump somehow made a deal? The only information the article has is:
It comes as the technology industry has pushed back against the Trump administration, amid mounting pressure to move manufacturing jobs back to the U.S. There will be no incentives from the federal government for the Intel project, the White House said.
Intel has a number of semiconductor fabrication plants in the US. In fact, they have 4 in Chandler, AZ. So, I think it is a good bet the Trump had little or nothing to do with the decision, but Intel is taking advantage of the politics.
