Farm workers labor in the fields south of Bakersfield, in Kern County, California's breadbasket, on April 9, 2025. As President Donald Trump's sweeping global tariffs took effect this weekend, US farmers hoping for a profit this year instead found themselves facing lower crop prices -- and the prospect of ceding more ground in foreign markets. US farms are losing the help of farmworkers as President Trump steps up mass deportations of undocumented workers after farmers in the US overwhelmingly voted for Trump. (Photo by Frederic J.

US President Donald Trump said Thursday that Los Angeles was "safe and sound" for the past two nights, crediting his deployment of thousands of troops to quell anti-deportation protests, as California prepared for a legal showdown over his unprecedented move. With protests spreading across the United States, a night-time curfew has been in place in its second-largest city with authorities tackling vandalism and looting that scarred a few city blocks.
