By Ted Hesson WASHINGTON (Reuters) -A U.S. civil rights group on Saturday sued to block the Trump administration from potentially transferring 10 migrants from the U.S. to a naval base in Guantanamo Bay,

Immigrant rights groups sued the Trump administration on Saturday in hopes of stopping the transfer of migrants from the U.S. to Guantanamo Bay.

The lawsuit says there is no legitimate reason to send migrants to Guantánamo because the U.S. has ample detention facility.

It’s their second legal challenge in less than a month over plans for holding up to 30,000 immigrants there for deportation.

Civil rights attorneys have filed a lawsuit against the Trump administration to prevent the transfer of undocumented immigrants from the United States to Guantánamo Bay, Cuba
