The “Late Night” host praised the president on April Fools’ Day.

Stephen Colbert was thrilled about President Donald Trump’s speech Wednesday from the White House. Really, no notes.

“It was concise, intelligent, and brought the nation together with shared purpose,” the comedian said in his monologue on The Late Show.

But then he couldn’t hold back the laughter, and the audience couldn’t keep quiet either. They knew what was coming.

“April Fools’!” Colbert said, then sounding more like himself.

He noted that the speech fell on the first night of Passover, “So, whether you’re Jewish or not, I recommend having had four glasses of wine.”

Colbert hadn’t seen the address, both because he was filming before the live event took place and, he joked, because he “put lamb’s blood on my TV, so the speech would pass me by.”

Trump delivered his first national speech since the beginning of the conflict with Iran live in primetime. He spoke for about 19 minutes, insisting that “core strategic objectives are nearing completion.”

The president also said that the U.S. planned to “hit them extremely hard over the next two to three weeks,” adding, “We are going to bring them back to the Stone Ages, where they belong.”

Trump also reiterated his projection that troops could finish their work within three weeks.

Anyone watching The Late Show would have known that Colbert is no fan of Trump, and vice versa.

The two have feuded in the past, particularly after CBS announced in July that Colbert’s show — actually the entire Late Show franchise — would not return after the season ends in May.

Afterward, Trump, who regularly lashes out at late-night hosts, posted on social media, “I absolutely love that Colbert got fired.”

To which Colbert responded, speaking into a camera labeled “eloquence cam,” that Trump should “Go f— yourself.”
