WASHINGTON (NBC NEWS) – Just hours after a continuing resolution passed to reopen the government following the longest shutdown in U.S. history, President Donald Trump sent out a series of tweets about his border wall deterring migrants from Central America, the indictment of former adviser Roger Stone and, of course, Hillary Clinton’s emails.

But as the government’s reopening grabbed headlines, Trump noted among his myriad tweets Saturday that time to resolve the dispute over his border wall was already ticking away.

“21 days goes very quickly. Negotiations with Democrats will start immediately. Will not be easy to make a deal, both parties very dug in,” Trump wrote.
