Trump: Federal Judge's Decision is 'Big Trouble' for US

WASHINGTON DC - US President, Donald Trump has vowed to overturn a legal ruling which suspended his ban on travellers from seven mainly Muslim countries. He described federal judge James Robart as a "so-called" justice whose "ridiculous" opinion "essentially takes law-enforcement away from" the US.

Judge Robart ruled on Friday that the prohibition was unconstitutional. A number of airlines have said they are allowing nationals targeted by the ban to board flights to America.

"The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!" Trump said on Twitter.

"When a country is no longer able to say who can, and who cannot , come in & out, especially for reasons of safety & security - big trouble!" he tweeted separately.

The US administration argues that his executive order last week, which caused confusion and anger, is designed to protect the US.

A chaotic Friday night set up a second weekend of widespread uncertainty over the controversial ban, this time with the administration on defense.

Trump's executive order suspended immigration from seven Muslim-majority countries for 90 days, the US refugee program for 120 days and indefinitely halted Syrian refugees from entering the United States.

The White House first called the judge's order "outrageous" and then dropped that word minutes later in a second statement.

"At the earliest possible time, the Department of Justice intends to file an emergency stay of this outrageous order and defend the executive order of the President, which we believe is lawful and appropriate," White House press secretary Sean Spicer said in a statement.

"The President's order is intended to protect the homeland and he has the constitutional authority and responsibility to protect the American people," he added.

Meanwhile, Dr Samuel Jacob, of the University of Pittsburgh Medical Center, was born in Syria. His Syrian wife has been unable to join him.

"I am going to meet with my attorney on Tuesday and he will know the latest information about whether my wife can try to come. It's hard to really understand the detail of this ruling without speaking to my lawyer and so I can't make a decision about what we can do until then," he said.

"I live and work hard every day in the US to serve everybody and save lives but at the end of the day I still get classified by the government as simply an "x" or a "y" and treated accordingly. I work hard for the US and I expect the USA to help me and protect me and let me be with my family, not be degraded in this way," he added.
