"SEE YOU IN COURT," Trump tweeted after his first executive order on immigration was stayed by a judge on February 3.
It would seem people have taken him at his word, given the number of complaints -- by states and rights groups -- filed against his travel ban. The new iteration is supposed to take effect Thursday.
It bars all refugees from entering the US for 120 days and halts the granting of new visas for travelers from six mostly-Muslim nations: Iran, Libya, Somalia, Sudan, Syria and Yemen for 90 days. Iraq was dropped from the initial list.
The White House reworked the first executive order to address some of the issues that came up in court. The revised order explicitly exempts holders of valid visas or legal permanent residents, for instance.

But the main points are largely the same.
The first version of the order, which Trump signed on January 27, triggered howls of protest at home and abroad as well as chaos at US airports as people were detained upon arrival and either held for hours or sent back to where they came from.
In recent days the president and his leading cabinet members -- Secretary of State Rex Tillerson, Attorney General Jeff Sessions and John Kelly, the homeland security secretary -- have defended the new order as a vital tool to preserve US national security and keep out extremists.
But critics say the order essentially remains a ban on Muslims and therefore unconstitutional as it singles out people of a certain religion for discriminatory treatment.
Critics argue that, even though the new order exempts holders of valid visas and permanent residents with so-called green cards, it will have a very negative effect on schools and universities and the business world, mainly the high tech sector, which employs many highly skilled immigrants.
The new battle against Trump's order is being played out on several geographical fronts, but mainly on the west coast, which tends to be heavily pro-Democrat.
