The White House said Monday that President Donald Trump would have breakfast with leaders of General Motors (GM - Get Report) , Ford Motor (F - Get Report) , and Fiat Chrysler Automobiles (FCAU - Get Report)  on Tuesday,  continuing the push to boost U.S. employment.

Trump spokesman Sean Spicer told reporters Trump "looks forward to hearing their ideas about how we can work together to bring more jobs back to this industry," according to wire reports. Trump during the campaign criticized Ford for its plans to move production to Mexico, and since winning the election has threatened on Twitter to impose significant tariffs on imported vehicles.

The rhetoric has produced some initial successes, with Ford canceling plans to build a new facility in Mexico and instead pledging to invest $700 million in Michigan and GM and Fiat Chrysler both announcing new investments of at least $1 billion apiece to revitalize U.S. plants. But the companies have all insisted that those decisions were made based on market dynamics and not because of lobbying from the President, and Ford remains committed to its plan to manufacture smaller, lower margin Focus sedans south of the border.

More recently executives at Kansas City Southern (KSU - Get Report) , the railroad that is responsible for a large share of cargo transit over the U.S./Mexican border, last week said that in private conversations customers have said they are not altering their plans in response to the new administration.

The meeting would come a day after Trump hosted another auto exec, Tesla Motors (TSLA - Get Report) CEO Elon Musk, who joined the president Monday morning along with some execs to discuss expanding the nation's manufacturing sector.

Ford CEO Mark Fields also attended that White House gathering.
