"He's promised me three big plants - big, big, big", said the president.
This time, months after many sounded off about the White House's travel ban from six predominantly Muslim countries, a number of leading tech CEOs had their say on Mr Trump's tweets this morning, which said that the U.S. military "will not accept or allow" transgender individuals to serve "in any capacity".
If Trump's statement is correct, that'd be a big investment on Apple's behalf and a significant change of pace.
Moving iPhone manufacturing to the USA would also likely push up costs which can not be in Apple's interests. Apple was one of the companies that came under fire from Trump, because it makes most of its products in China.
Foxconn chairman Terry Gou plans to join Trump, Ryan, Wisconsin Gov. Scott Walker, and Vice President Mike Pence at the White House to make the announcement about the Kenosha, Wisconsin, plant. This way, Apple aims to support the company's manufacturing efforts.
Cook explained this issue himself in a "60 Minutes" interview in 2015: "China put an enormous focus on manufacturing".
As Bloomberg points out, Apple doesn't build or manage factories; instead, it operates an intricate Asian network of production.
The development can be seen as a major victory for Trump's much publicized pro-American business policies where he envisaged domestic companies set up manufacturing in the country to help revive the economy. Recently, Apple invested $200 million in Corning, iPhone cover glass supplier.
Cook is said to have asked its main Asian assemblers Foxconn, Pegatron and Wistron to look at putting plants in the USA.
