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.

After a federal judge in Los Angeles barred “roving patrols” by immigration agents in seven California counties, the Trump administration asked the 9th Circuit Court of Appeals to resume operations that lawyers for the state have argued are unconstitutional.

The lawsuit accused the DHS of operating a program of “abducting and disappearing” community members using unlawful arrest tactics.
