Trump would have to literally kill all lawyers. Think of the DoJ as a pile of folks who all took an oath to the law itself. When pundits complain that it's being "weaponized", they're actually talking about a facet of overcriminalization where the DoJ's limited attention can be controlled somewhat; it's always going to be a full-power laser that targets what the law perceives as criminality.
In particular, the President doesn't have the authority to tell the DoJ to stop an investigation, and the DoJ usually can't tell individual prosecutors to stop filing motions. Trump wasn't able to protect Cabinet member and Teapot Dome Candidate #2 Michael Flynn from prosecution, nor can he protect Eric Adams. The worst that he can do is a Saturday Night Massacre, where he fires lawyers until the investigations stop, and the entire pattern of special counsel is purpose-designed to prevent that from actually working.
I wasn't going to explain my downvote, but it's been a few days and apparently everybody here is thinking about MRAs when there's more at stake.
I see Nixon in Trump: somebody who starts and prolongs wars for their own political gain. Of my three uncles who qualified to go to Vietnam, one was permanently disabled during basic training, one didn't come back home, and one fell apart before I was born. I had to "voluntarily" register as a potential servicemember in order to access various standard government services as a young man in the 2000s, while the USA was invading Iraq and Afghanistan. Under a sufficiently fascist government, the USA has shown itself capable of sending its men to death. This system is explicitly misandrist; only men are required to register and only my uncles suffered this hate.
Misandry isn't equal and opposite to misogyny. Our society was never obligated to hate men and women in ways that are nicely symmetric and amenable to analysis; indeed, critical theory suggests that society deliberately structures itself to obfuscate its hate.
