‘Disgraceful’: DJ Daniel, 13-year-old cancer survivor honored by Trump, has plenty to say about Al Green, Elon Musk and Rachel Maddow

Democrats who disrespected Donald Trump at his joint address to Congress have made an enemy of the country’s youngest honorary Secret Service agent, Devarjaye “DJ” Daniel.

“They make me mad,” the 13-year-old cancer survivor told The Post. “If you’re not going to say something nice, you don’t need to be there. Honestly, if it was up to myself, and I was the president, I would literally stop what I was doing, escort [disrespectful people] out and have them banned. They wouldn’t be allowed back in. My dad says that you can’t reward bad behavior.

“Even if they don’t like President Trump, they need to respect the position.”

DJ, who was sworn in before Trump’s speech Tuesday, said the disruption by Rep. Al Green (D-Texas) — which got him booted from the House chamber and censured by fellow lawmakers on Thursday — hit particularly close to home.

“[Al Green] embarrassed us; he’s from our congressional district,” said DJ, who lives with his dad in Houston. “I’d tell him that he was very disgraceful and very disrespectful.”

DJ, who is battling brain cancer, won the nation’s heart when he was singled out by the president as “a young man who truly loves our police.” The teen and his dad, Theodis Daniel, a retired Navy man, were also invited to the Oval Office for a Wednesday sit-down with President Trump.

“As soon as I saw him, I gave the president a big hug,” said DJ. “He said that he’s proud of me and handed me a signed hat.”

But “I’m not going to wear it,” he added. “It’s a collector’s item and is valuable.”

He has been made an honorary member of nearly 1,000 police departments around the US, including ones in New York and New Jersey.

“I was in Joisey,” he said, putting on a “Sopranos” accent. “[Officers there] can be a little feisty and they kind of rubbed off on me.”

During his VIP visit to Washington DC, DJ met a lot of people. And while he is not one to play favorites — “They were all great,” he diplomatically said — one notable figure in particular struck a chord.

“While in the White House, I was walking around and magically, deliciously ran into Elon Musk; we took a picture,” DJ said of the world’s richest man. “He’s a party dude and strictly business. He has the hands to fix America.”

Asked if he had a message for the man behind DOGE, DJ replied, “Keep doing what you’re doing and keep up the good work.”

He has less encouraging words for Rachel Maddow, who called President Trump “disgusting” for highlighting DJ as a cancer warrior.

“If you have nothing nice to say,” DJ scolded, “then don’t say anything at all.”

And his message to Trump? “Thank you for saving the United States.”
