Following Trump’s revelation, Biden tweeted that he’d also had some “MAJOR ANNOUNCEMENTS the last couple of weeks.”

He went on to list “Inflation’s easing,” “I just signed the Respect for Marriage Act,” “We brought Brittney Griner home,” “Gas prices are lower than a year ago” and “10,000 new high-paying jobs in Arizona.”

Other Twitter users soon joined the conversation, with some mocking Trump while others took aim at Biden’s record in government.

A number made reference to “Dark Brandon,” a right-wing meme suggesting the president is evil which was later adopted ironically by some of his supporters.

Jon Favreau, who worked as a speechwriter for former President Barack Obama, responded: “Dark Brandon was made to be NFT’d.”

Trump’s trading cards were created as NFTs, or non-fungible tokens, meaning they’re pieces of online art with their ownership certified by blockchain technology.

One Twitter user posted an edited painting depicting Biden wearing aviator sunglasses, adding: “Dark Brandon stays winning!”

Jenna Ellis, a former Trump campaign legal advisor and Newsmax contributor, replied: “But no NFTs??” followed by a clown face emoji.

Voice actor David Kaufman tweeted at Biden: “JOE BRINGING THE SHADE!!!!”

Another Twitter user posted an edited photo of Biden pointing and laughing, with the caption: “TRADING CARDS? THAT’S HILARIOUS.”

Others responded to Biden’s post by criticizing his performance as president.

A person who describes himself on Twitter as a Trump supporter reposted a video that appears to show hundreds of migrants at America’s southern border.

Another Twitter user posted a photo of a carton of 12 eggs being sold for $8.99, adding: “What happened with the build back better?”

Twitter user Mike Conley Jr. wrote: “Inflation is not easing. You finally did something good. You traded the merchant of death for a pot head athlete, and you should be in prison for that. Every life that is taken from his release is on your hands. Can’t brag about lowering prices when you were responsible for em.”

Trump’s NFT announcement angered some of his supporters within the conservative movement, with his former White House advisor Steve Bannon saying whoever was responsible for the announcement should be “fired today.”

Conservative activist and film director Robby Starbuck wrote: “Hard truth time: This is not good. We’re facing a threat to civilization from far left Marxist extremists. Teasing NFT cards as a major announcement is not the kind of fight people want to see now. These are dark times. Love the guy but this turns many off. Agree or disagree?”

A poll released before the announcement found Trump’s popularity had slumped to its lowest level in seven years.

The Quinnipiac University survey recorded just 31 percent of registered voters as having a positive view of Trump, versus 59 percent with a negative view, his worst figure since July 2015.
