Trump shows his notes during press briefing as viewers try to see what it says

Donald Trump was not too careful during a recent press briefing in the Oval Office after cameras picked up notes that were seemingly not for public viewing.

The president was speaking in the White House after singing an executive order that would task federal government with determining who will receive a mail ballot during elections.

Trump has long expressed his desire to remove the option for a postal vote, though it was the topic of a judge's decision to pause the construction of his $400 million ballroom in the White House that was the top of his agenda.

Many flocked to Reddit to discuss what they think Trump's notes said, with many coming to the conclusion it's a summary of what U.S. District Judge Richard Leon said on Tuesday about the ballroom.

"There was a judgement against it today, so it makes sense," one person penned on social media.

The judge prohibited “any further demolition, site preparation work, landscape alteration, excavation, foundation work, or other construction or related work, other than actions strictly necessary to ensure the safety and security of the White House and its grounds, including the ballroom construction site, and provide for the personal safety of the President and his staff."

He added: "The president of the United States is the steward of the White House for future generations of First Families. He is not, however, the owner!"

Many others on Reddit suggested that Trump not use a sharpie in the future, as such use of the type of pen more than likely led to the notes looking very obvious.

In the press briefing where Trump's notes were on show for all to see, the president spoke about his latest executive order that he's signed to shape how elections across the US are run.

"It’s about voter integrity, we want to have honest voting in our country because if you don’t have honest voting, you can’t have really a nation," the Republican president told press.

Commerce Secretary Howard Lutnick, who stood alongside Trump in the Oval Office, added: "The states run these elections – if they want to use the US mail, the US Postal Service, they’re going to get a code, a bar code, from the US Postal Service and they’re going to put that on the envelope and we will have one envelope per vote."
