The President is supposed to keep out of politics. Why?? Because he is supposed to represent all of the people which means he’s supposed to represent Donald Trump too but he’s been working against him.
Obama is using his position as President to work against Donald Trump. That fits the definition of corruption, “the use of power by government officials for illegitimate private gain”.
Corruption requires four things.
1. Use of Government Power.
2. By a government official.
3. Illegitimate gain.
4. Private gain.
It’s #4, private gain because Obama personally want’s Donald to lose. That’s #3, illegitimate. Plus Obama is using the power of the President, #1 and Obama is a government official. That’s #2.
So #1,#2,#3,and #4. Guilty of all four things needed to be corrupt.
