HBO’s “Real Time” host Bill Maher hilariously attacked President Donald Trump for a declaring a national emergency to build his border wall after Mexico and Congress refused to fund his plan.

“Try to remain calm, there’s a national emergency, haven’t you heard?” he asked.

“He did it, f*cko did it today,” Maher said. “The president declared a national emergency.”

Maher ridiculed Trump’s Rose Garden press conference announcing the declaration.

“This was just completely crackers,” he said. “I know I’ve said that before, but this was just one long, baseless, incoherent, stream of consciousness, call the nursing home rant.”

“We don’t even notice anymore when he gets stupider, it’s like farting on a garbage ship,” he continued.

“You know who should’ve declared a national emergency long ago? Fact checkers,” Maher joked.

“A national emergency should not be used by Trump — it should be used on Trump,” he concluded.

He went on to joke about Sen. Mitch McConnell (R-KY), Melania Trump’s sex life, and Fox News personality Sean Hannity.
