"I spoke to [Cook], he's promised me three big plants-big, big, big," Trump told the Journal.
This isn't the first time that Trump has said he talked to Cook about a big manufacturing facility. During his campaign, Trump called several times for Apple to build its products in the United States.
In January, Trump said that Cook had "his eyes open" to building a manufacturing facility in the United States.
Of course, Apple doesn't do any of its own manufacturing, save for some Mac Pro production in Texas. It contracts with big manufacturers like Foxconn to build its iPhones and other computers, mostly in China.
Foxconn is expected to make an announcement about building United States-based manufacturing in states including Wisconsin and Michigan as soon as Wednesday, the Milwaukee Business Journal reported on Tuesday.
Apple declined to comment to the Wall Street Journal.
