In his own words

Trump had thoughts about and words for anyone handling classified national security documents before he violated the laws regarding the same.

Some are recorded in the Mar-a-Lago documents case indictment:

TRUMP's Public Statements on Classified Information 

23. As a candidate for President of the United States, TRUMP made the following public statements, among others, about classified information:

a. On August 18, 2016, TRUMP stated, “In my administration I'm going to enforce all laws concerning the protection of classified information. No one will be above the law."

b. On September 6, 2016. TRUMP stated, “We also need to fight this battle by collecting intelligence and then protecting, protecting our classified secrets... We can't have someone in the Oval Office who doesn't understand the meaning of the word confidential or classified.”

c. On September 7, 2016. TRUMP stated. “[O]ne of the first things we must do is to enforce all classification rules and to enforce all laws relating to the handling of classified information.”

d. On September 19, 2016, TRUMP stated, “We also need the best protection of classified information.”

e. On November 3, 2016, TRUMP stated, “Service members here in North Carolina have risked their lives to acquire classified intelligence to protect our country.”

24. As President of the United States, on July 26, 2018, TRUMP issued the following statement about classified information:

As the head of the executive branch and Commander in Chief, I have a unique Constitutional responsibility to protect the Nation's classified information, including by controlling access to it. More broadly, the issue of [a former executive branch official's] security clearance raises larger questions about the practice of former officials maintaining access to our Nation's most sensitive secrets long after their time in Government has ended. Such access is particularly inappropriate when former officials have transitioned into highly partisan positions and seek to use real or perceived access to sensitive information to validate their political attacks. Any access granted to our Nation's secrets should be in furtherance of national, not personal, interests.

36. In August or September 2021, when he was no longer president, TRUMP met in his office at The Bedminster Club with a representative of his political action committee (the“PAC Representative”). During the meeting, TRUMP commented that an ongoing military operation in Country B was not going well. TRUMP showed the PAC Representative a classified map of County B and told the PAC Representative that he should not be showing the map to the PAC Representative and to not get too close. The PAC Representative did not have a security clearance or any need-to-know classified information about the military operation.

37. On February 16, 2017, four years before TRUMP's disclosures of classified information set forth above, TRUMP said at a press conference:

“The first thing I thought of when I heard about it is, how does the press get this information that's classified? How do they do it? You know why? Because it's an illegal process, and the press should be ashamed of themselves. But more importantly, the people that gave out the information to the press should be ashamed of themselves. Really ashamed.

Or you can let it be read to you here. 

The whole thing is an amazing account of bald-faced arrogance and incredible ignorance on the part of a former president of the US, who should obviously never have been near the office, and proof of his illegal activity surrounding classified documents and attempt to cover it up, including directing his minions to destroy security camera video and hiding evidence from his own attorneys. 

And Republicans want to put him back in office.
