In a court document, it said it intends to seek a temporary restraining order against Donald Trump's new executive order restricting travel from six Muslim-majority countries.
The Trump administration this week issued the new executive order, replacing an earlier, more-sweeping one that was successfully challenged in court by the state of Washington.
The new order, will keep a 90-day ban on travel to the United States by citizens of six Muslim-majority nations: Iran, Libya, Syria, Somalia, Sudan and Yemen.
