The U.S. Chamber of Commerce launched a new lobbying campaign on Monday to illustrate the ways that the Trump administration's tariffs can hurt every state in the nation economically.

Why it matters: The nation's biggest business group — with 3 million members, per Reuters, who first reported the campaign — is usually an ally of the Republican Party and its politicians. And it has previously advocated for economic moves from the administration, like the GOP's new tax law, so its opposition is striking.
