Donald Trump returned to one of his favorite subjects Monday morning with Yet Another Wall Tweet, this one even more nonsensical than the usual:

x We would save Billions of Dollars if the Democrats would give us the votes to build the Wall. Either way, people will NOT be allowed into our Country illegally! We will close the entire Southern Border if necessary. Also, STOP THE DRUGS! — Donald J. Trump (@realDonaldTrump) December 3, 2018

As Politico’s Caitlin Oprysko characterized it, he said this “without explaining how his elusive border wall would create a savings bonanza,” and “did not elaborate on his claim that erecting a border wall would result in savings for the country.” That’s the objective reporter-ese for “Trump lied again. Pulled that right out of thin air.” Because … save money? Is that the new “Mexico will pay for it”? Or is he just confused about the tens of billions of dollars a border wall would cost? Nah, he’s lying, and enough of his fan base will lap it up to make him think the lie was worth it.

Since the Supreme Court refused to take up a challenge to Trump’s constitutional authority to build a wall, it’s up to congressional Democrats to deny Trump the funding to erect this monument to his bigotry.
