U.S. District Court Judge Ann Donnelly halted removal of people who were detained after Trump's order to ban all immigrants from seven countries entering the U.S. The countries are Syria, Libya, Iraq, Iran, Yemen, Sudan, and Somalia. All of those countries have Muslim majorities.

What this ruling says is that people who arrived on U.S. soil with valid transit visas or who had previously been accepted as refugees in the country, now have the (temporary) right to stay in the U.S. Her decision preserves the status quo and ensures that people who have been granted permission to be in this country are not illegally removed off U.S. soil.

Trump's order on Friday (27th Jan, 2017) barred people from Syria indefinitely and denies entry for 90 days from the other six countries. It also halted the resettlement of all refugees for four months.

ACLU Executive Director Anthony D. Romero said that "Our courts today worked as they should as bulwarks against government abuse or unconstitutional policies and orders. On week one, Donald Trump suffered his first loss in court."

Trump's comments about his order - "It's working out very nicely. You see it in the airports, you see it all over. It's working out very nicely and we are going to have a very, very strict ban and we are going to have extreme vetting, which we should have had in this country for many years."

Judge Ann Donnelly was confirmed to her judgeship in 2015 by president Barack Obama.
