WASHINGTON, July 13 (Reuters) - Federal officials on Sunday defended President Donald Trump 's escalating campaign to deport immigrants in the U.S. illegally, including a California farm raid that left one worker dead, and said the administration would appeal a ruling to halt some of its more aggressive tactics.

A White House spokesperson told CBS News Los Angeles that the order was a "gross overstep of judicial authority."

The union said the judges were working in courts in 10 different states across the country — California, Illinois, Louisiana, Maryland, Massachusetts, New York, Ohio, Texas, Utah and Virginia.
