Trump would have had his travel order months ago if he had written it properly so it was not merely "probably" unconstitutional. The news mentioned the 6 countries in Trump's order and the 7 countries in Obama's order-- how did Obama's order pass and Trump's did not? Trump is banning people from six countries, while Obama was checking everybody for travel to the 7 countries regardless of where they came-- because terrorists could come from anywhere, even Canada, the UK, or Mexico-- what is important is whether they went to radical Islamist indoctrination or training camps in 7 countries (or 6 in Trump's case). BTW the rulings against Trump's order are only temporary-- and that is all that Trump had to get by until getting the case heard at the Supreme Court.
