President Donald Trump's escalating trade war is having an impact across the United States. Take, for example, Spartanburg, South Carolina, home to a BMW plant that's the number one car exporter in the country. BMW came to the area in 1992, in part, to avoid tariffs. But now, everything could be changing. Martin Savidge has the story.

It may not look like it but Spartanburg, South Carolina is a war zone - a trade war thanks to the president most folks here voted for. Spartanburg is home to the largest BMW plant in the world. Last year they made more than 370,000 luxury SUVs, employing 10,000 people, pumping billions into the state's economy.

MARTIN SAVIDGE SPARTANBURG "Is it safe to say how well BMW does? Is how well Spartan county does?"

JESSE JONES, RESIDENT SPARTANBURG "You might say that because there's a lot of industry in Spartanburg County that's directly connected to BMW."

MARILYN SAUCEDO, RESIDENT SPARTANBURG "Growth. Jobs. And I know that that's brought in a lot of families into the area. It brings money into the area."

Spartanburg is also deep red, meaning in 2016 the county voted 63 percent for Donald Trump. But President Trump has threatened to place tariffs on imported BMW vehicles and parts. That could make BMWs made and sold in America a lot more expensive. The company is already feeling the impact of Trump's trade war with China. Over 80,000 Spartanburg-made BMW SUVs are sold in China every year. Now China is striking back, placing tariffs on the American made vehicles. It's an economic double whammy of Trump's making which BMW says could have negative effects on investment and employment in the United States. In other words, BMW might have to scale back production and lay off workers in Spartanburg.

DAVID BRITT, COUNTY COMMISSIONER SPARTANBURG "I feel like I birthed BMW."

David Britt is Spartanburg County Commissioner and a Trump backer.

DAVID BRITT, COUNTY COMMISSIONER SPARTANBURG "I'm extremely concerned because the impact, the ripple effect, is - it goes beyond BMW and the automotive industry."

Britt is one of the few Republican politicians in the country willing to tell Trump he's wrong.

DAVID BRITT, COUNTY COMMISSIONER SPARTANBURG "These tariffs could put the foot on the throat of growth and stop it. We don't need that."

Other Trump supporters we talked to here say they support the president's policies, but some are concerned. None wanted to talk on camera. And they're not the only ones reluctant to speak out. Many South Carolina companies are also concerned but fear if they criticize the president's policies they'll become a target of his twitter wrath, much like what happened to Harley Davidson.

TED PITTS, PRESIDENT S.CAROLINA CHAMBER OF COMMERCE "I think the President has shown that you're better off working with his administration on issues to help them understand it and allow them to get to the right answer."

Ironically Trump's tough talk on trade was part of his appeal to voters in South Carolina. Now there's growing concern Trump's trade war is about to backfire on them and possibly eventually on him.

TED PITTS, PRESIDENT S.CAROLINA CHAMBER OF COMMERCE "I don't see this issue change in voters minds. Now if you look down the road and there are concerns."
