The campaign launching Monday will focus on how Trump’s tariffs targeting goods from China, Canada, Mexico and the European Union could affect each U.S. state, Reuters reported.

For example, South Carolina could see $3 billion worth of exports targeted by retaliatory tariffs, the Chamber told Reuters.

The Chamber has regularly been an ally to Republican presidents, lobbying for lawmakers to back the GOP tax law last year and set to tout the tax cuts in ads leading into the 2018 midterms.

The campaign comes as Trump slaps billions of dollars worth of tariffs on exports from other countries, including historic U.S. allies such as Canada.

Canada on Sunday announced $13 billion in its own tariffs on American exports.

“The administration is threatening to undermine the economic progress it worked so hard to achieve,” Chamber President Tom Donohue said in a statement to Reuters. “We should seek free and fair trade, but this is just not the way to do it.”

Critics have referred to Trump’s tariffs as part of an escalating trade war.

Trump has insisted the tariffs are needed to protect American industries.
