The master of nicknames – who can forget such classics as “Crooked Hillary” and “Little Marco” – has a new one for the partial government closure: it’s now the “Schumer Shutdown,” complete with hashtag, reflecting President Donald Trump’s belief that Democratic leadership intransigence is the main cause of 800,000 federal workers not receiving their regular paychecks.

The Commander-in-Tweet rubbed it in during his early Sunday messages, accusing his rivals of not being concerned “about the safety and security of Americans!”

Both sides are expected to resume bargaining on a new budget in the New Year, but positions are hardened and mostly center on whether funding for Donald Trump’s wall on the southern border will be part of a new deal.

The tweetstorm so far:

President and Mrs. Obama built/has a ten foot Wall around their D.C. mansion/compound. I agree, totally necessary for their safety and security. The U.S. needs the same thing, slightly larger version! — Donald J. Trump (@realDonaldTrump) December 30, 2018

Great work by my Administration over the holidays to save Coast Guard pay during this #SchumerShutdown. No thanks to the Democrats who left town and are not concerned about the safety and security of Americans! — Donald J. Trump (@realDonaldTrump) December 30, 2018
