New Trump immigration order won't have blanket ban on Iraq, sources say

The original order was temporarily halted in early February.

The newly revised order, made to replace a prior order that limited travel and immigration from seven predominantly Muslim countries in the Middle East and Africa, was expected Wednesday after a federal court judge temporarily halted the original order in early February.

However, Wednesday came and passed without the order's signing, a delay that ABC News has learned was due in part to concerns expressed by members of Trump's own Cabinet.

These officials familiar with the new draft order also tell ABC News the measures may not take effect immediately as the first one did -- a situation that caused disorder at multiple airports as law enforcement officials detained travelers who were impacted. Instead, the new order could delay implementation for up to two weeks from the days it’s issued.

Furthermore, the order will only apply to future visa applicants, according to these officials. All current U.S. visa holders -- even those from the banned countries -- will be allowed to travel to the country. Under the previous order, even those with valid U.S. visas could not reenter the country if they came from one of the seven banned countries.

Multiple officials with knowledge of the situation said that it is likely to come next week.
