President Donald Trump praised Ford Motor Co. on Twitter early Tuesday for the company's expected announcement later in the day on investments and jobs at its U.S. plants. Trump said the automaker would be making a major investment in three of its Michigan manufacturing facilities. 

"Big announcement by Ford today. Major investment to be made in three Michigan plants. Car companies coming back to U.S. JOBS! JOBS! JOBS!" Trump tweeted early Tuesday. 

According to earlier reports, Ford was expected to invest in its Michigan assembly plants in Wayne and Flat Rock, as well as the Romeo engine plant. However, it was unclear by Trump's tweet if the company would make an announcement about new plans or if it was about work on previously planned investments. The number of jobs to be created following the "big announcement" also remained unclear.

The investment announcement comes less than two weeks after Trump pushed leaders from the auto industry to discuss ways of keeping jobs in the U.S. In January, Trump met with General Motors Co. CEO Mary Barra, Ford's Mark Fields and Fiat Chrysler Automobiles NV's Sergio Marchionne to discuss the matter.

The president also teased in one of his tweets in February that a big auto industry announcement was coming last week of March, however, it is not confirmed if the Ford announcement is the same. 

While Ford reportedly declined to comment on the latest investment, it said in January it would invest $700 million in Flat Rock and create 700 new jobs in Michigan, while also scrapping plans to build a $1.6 billion plant in Mexico.

Ford CEO Fields had expressed confidence in the Trump presidency after their meeting in January. 

“Walking out of the meeting today, I know I come out with a lot of confidence that the president is very, very serious in making sure the United States economy is going to be strong and have policies — tax, regulatory or trade — to drive that,” Fields said at the time. “That encourages all of us, as CEOs, as we make decisions going forward. So it’s a very, very positive meeting.”
