Is Lee Jae-myung actually from a legal background?

Even Yoon Suk-yeol, who failed the exam nine times, didn't know the law well.
President Lee Jae-myung, who is said to be a former lawyer, is also facing endless obstacles.
When did he ever neutralize the presidential appointment power?
The President does not have the right to demand a re-nomination.
Where in the Constitution does it say such a thing?
The National Assembly should decide whether to approve or disapprove Cho Hee-dae's nomination proposal,
and the President can either accept the proposal approved by the National Assembly or refuse the appointment.
If you don't like it, ask the Constitutional Court for a ruling. Stop whining.
They haven't even read the revised Criminal Procedure Act, and their understanding of the spirit of the law is a mess.
When I saw them asking if it's written somewhere that prosecutors shouldn't investigate, I thought, 'Are they crazy? Or just ignorant?'
