Washington state Attorney General Bob Ferguson heard the news about the latest travel ban ruling while in his own hearing before Seattle federal Judge James Robart.

Judge Derrick Watson of Hawaii granted a temporary restraining order late Wednesday afternoon, putting the Trump administration's revised executive order on hold before it was scheduled to take effect at midnight.

"Bottom line, that is fantastic news—that is exactly what we’re seeking," said Ferguson shortly after the decision came down.

However, Robart denied a motion by the Attorney General to apply the existing temporary restraining order granted last month, which halted the initial order, to the new order.

"Judge Robart did say in his brief comments that he thought there were significant differences between the orders," explained Ferguson outside of court.

Ferguson has also acknowledged significant changes between the two orders, but argues that the two key provisions suspending new visas and the refugee program pose the same constitutional concerns.

As a result, he's now requesting a new temporary restraining order that would apply to the second version of the order.

Robart has not yet issued a decision on that part of the case.

"We understand the judge has a lot of paper in front of him. It’s a complex case, and now he has developments in Hawaii, so we respect whatever his timeline is," Ferguson told reporters.

The Attorney General also said he will respect Robart's decision, however he rules.

"Sometimes judges will issue overlapping injunctions, other times they will decide that it renders the issue the moot and there’s no need to rule. It will be up to judge Robart to decide," added Solicitor General Noah Purcell of the possibilities.

Trump's revised ban suspends new visas for people from six predominantly Muslim countries for 90 days: Somalia, Iran, Syria, Sudan, Libya, and Yemen. It also temporarily shuts down the U.S. refugee program for 120 days.

Robart issued a restraining order February 3, against the initial ban, a ruling that was later upheld by the U.S. 9th Circuit Court of Appeals.
