A Taiwanese billionaire who pledged to invest billions of dollars to create jobs in the United States after President Trump was elected spent more than two hours visiting White House officials on Thursday.

Foxconn Chairman Terry Gou, whose company manufactures the Apple iPhone in China, declined to confirm whether he met with Trump, when asked by a Washington Post reporter as he exited the complex with several aides.

“My memory is not good; maybe I already forgot,” Gou said.

Foxconn, an electronics manufacturing giant with more than 1.2 million employees in China, had pledged in 2013 to invest $30 million and hire 500 workers for a new high-tech factory in central Pennsylvania, a project that has languished. After Trump was elected, Foxconn made a new commitment to invest $7 billion to hire 50,000 U.S. workers, part of a flurry of economic pledges from large companies that Trump and his team rounded up in a bid to boost jobs, a key campaign promise.

On Saturday, his 100th day in office, Trump will hold a campaign rally in Harrisburg, Pa., the city where Foxconn has failed to build the high-tech factory it promised four years ago.

“We are made in America,” Gou said in response to the Post reporter's question about what he discussed at the White House. “We sign a contract, we will let you know.”

A meeting with Gou was not listed on the president's public scheduled released by the White House on Wednesday night. A senior administration official said before Gou arrived that he did not know of his visit.

It was not clear whether the White House was preparing to make a new announcement about Foxconn's investment promises, but the administration has been racing to show progress on its agenda ahead of the 100-day milestone.
