The Associated Press reports that General Motors will announce a $1 billion investment in factories, which in turn will either create or keep 1,000 jobs.

A.P. adds that multiple factories are expected to receive a portion of the investment, but specific factory locations are not expected to be named in the expected Tuesday morning, Jan. 17 announcement.

This news comes on the heels of President-elect Donald Trump threatened GM and Toyota with import taxes through Twitter. The reported GM announcement would come two weeks to the day after Ford Motor Co. said it would scrap plans for a Mexico plant, and instead invest $700 million in the Flat Rock Assembly Plant.

The A.P. report states that this investment from GM is part of the normal process in preparing factories for new vehicle models, "and it's been planned for months." The source feeding A.P. with this information has reportedly asked to remain anonymous.

When the Chevrolet Traverse was revealed at the North American International Auto Show in Detroit, GM said that the new model would be built in Lansing.

On Jan. 3, the same morning of the Ford announcement, Trump targeted GM by threatening to tax the automaker for importing cars to the U.S. from Mexico.

The automaker did import Cruze sedans from Mexico last year, but all sedans are now made stateside, according to GM spokesperson Patrick Morrissey.

The spokesperson told A.P. that the number of cars imported from the Mexico plant only amounts to a small percentage of the some 172,000 sold through November 2016. The automaker reports it only sold around 4,500 of the Cruze hatchbacks in the U.S. last year.

In early December, GM CEO Mary Barra was selected for Trump's economic advisory group, which will offer the president-elect ideas on how to create jobs and economic growth.

When Barra was asked about the president-elect's tweets at the Detroit auto show, she told A.P. that the automaker did not have plans to change where it makes small cars.
