SACRAMENTO, CA – California Governor Gavin Newsom has announced his intention to sue the Trump administration over what he describes as "illegal tariffs" imposed on U.S. trading partners worldwide. The governor's announcement, made on the 16th (local time), highlights the severe economic repercussions these tariffs are having on California's households, businesses, and overall economy.

"President Trump's unilateral and disruptive tariffs are placing California families and businesses at significant risk, accelerating price increases and causing job losses," Governor Newsom stated. "We cannot stand idly by while the federal government undermines our economic stability. We will take this fight to the courts."

The governor's office released a statement emphasizing the scale of the impact, noting that California, as the largest state economy in the United States, is disproportionately affected by these trade policies. "California's ports handle approximately 40% of all U.S. imports, with a substantial portion originating from China," Newsom explained. "The imposition of these tariffs creates a ripple effect, disrupting supply chains and increasing costs for consumers and businesses alike."

Newsom's legal challenge will focus on the International Emergency Economic Powers Act (IEEPA), the legislation under which the Trump administration has justified its tariff actions. The state will argue that the president has overstepped his authority in invoking this act to impose sweeping tariffs without proper congressional oversight.

"Donald Trump does not have the authority to impose such destructive and chaotic tariffs on all countries. The U.S. will continue to lose too much," he reiterated on his X account. "This is about protecting American families and our economic future."

California's position is bolstered by its significant role in international trade. The state's two major ports, Los Angeles and Long Beach, serve as critical gateways for goods entering the U.S., making it particularly vulnerable to trade disruptions. The state's robust agricultural sector, technology industry, and manufacturing base are also heavily reliant on international trade, with Mexico, Canada, and China being key export markets.

Data provided by the governor's office reveals that in 2024, these three countries accounted for approximately $67 billion of California's $183 billion in total exports, representing a substantial portion of the state's economic activity. This highlights the potential damage that tariffs can inflict on California's economy.

California's lawsuit marks the first state-level challenge to the Trump administration's trade policies, underscoring the growing tension between state and federal authorities on economic matters. The state's legal action is expected to draw significant attention from other states and industries impacted by the tariffs.

The "Golden State," as it is known, is not only the most populous state in the U.S. but also a major hub for international commerce, handling approximately $675 billion in two-way trade. This trade activity supports millions of jobs across the state, making the stability of international trade crucial for California's economic well-being.

The lawsuit filed in the U.S. District Court for the Northern District of California will argue that the tariffs violate the IEEPA and exceed the president's constitutional authority. California's legal team is expected to present evidence of the economic harm caused by the tariffs, including increased costs for businesses, reduced export opportunities, and potential job losses.

This legal challenge comes at a time when the U.S. economy is facing numerous uncertainties, including global trade tensions and domestic economic challenges. California's action reflects a broader concern among state and local governments about the impact of federal trade policies on their economies.

Governor Newsom's decision to sue the Trump administration highlights the state's commitment to protecting its economic interests and challenging federal policies that are deemed harmful. The outcome of this legal battle could have significant implications for the future of U.S. trade policy and the balance of power between state and federal governments.
