California Governor Gavin Newsom filed a lawsuit against President Donald Trump, seeking to halt the implementation of a series of tariffs as part of the president’s protectionist trade agenda. This action marks the first time a state has directly challenged the Trump administration’s broad tariff plans, which have significantly impacted global trade markets and sparked tensions between the US and its trading partners. Governor Newsom asserts that Trump lacks the authority to impose such significant tax hikes unilaterally, claiming these tariffs inflict immediate and irreparable harm on California’s economy, the nation’s largest by GDP, a powerhouse in tech innovation and agriculture.
