Two senior White House officials told NBC News that President Donald Trump plans to sign a revised version of his executive order that restricted travel from seven Muslim-majority nations on Monday.

Since a federal judge in Seattle issued a temporary restraining order on it in early February, different White House officials and the president have stated numerous times that the new executive order would be signed soon. But more than a month after it was barred, the revised version has not been realized.

The delay would seem to undercut the White House’s original argument for its swift execution, which created confusing travel situations and immigration statuses for hundreds of people the weekend it was implemented. When its necessity and legality was challenged, the president and senior administration officials emphasized the need for travel restrictions because they believed the nation would be at risk without them.

These are the developments since the executive order was first signed.
