There is a federal crime of bribery, 18 USC 201 that makes it a crime to
directly or indirectly, corruptly gives, offers or promises anything
of value to any public official or person who has been selected to be
a public official, or offers or promises any public official or any
person who has been selected to be a public official to give anything
of value to any other person or entity, with intent— (A) to influence
any official act; or (B) to influence such public official or person
who has been selected to be a public official to commit or aid in
committing, or collude in, or allow, any fraud, or make opportunity
for the commission of any fraud, on the United States; or (C) to
induce such public official or such person who has been selected to be
a public official to do or omit to do any act in violation of the
lawful duty of such official or person
If the president of the US is a public official or person who has been selected to be a public official, this might be a crime. (I said might, I did not say is: let's first determine if POTUS is one). That section also says
For the purpose of this section— (1) the term “public official” means
Member of Congress, Delegate, or Resident Commissioner, either before
or after such official has qualified, or an officer or employee or
person acting for or on behalf of the United States, or any
department, agency or branch of Government thereof, including the
District of Columbia, in any official function, under or by authority
of any such department, agency, or branch of Government, or a juror;
(2) the term “person who has been selected to be a public official”
means any person who has been nominated or appointed to be a public
official, or has been officially informed that such person will be so
nominated or appointed
POTUS is not a Member or Congress, etc: is POTUS "an officer or employee or
person acting for or on behalf of the United States, or any
department, agency or branch of Government thereof". Is POTUS "an officer", or "an employee"? 18 USC 202 gives a terminological flow chart for specific sections of 18 USC Ch. 11, stating that
Except as otherwise provided in such sections, the terms “officer” and
“employee” in sections 203, 205, 207 through 209, and 218 of this
title shall not include the President...
§201 is not included in this list of exclusions; but it is also not explicitly included: the law simply does not say.
The problem is that this chapter treats POTUS in three ways. For some sections, he is explicitly not an officer or employee; for one section he is explicitly a covered government person; and for §201, the law does not do not say. Regarding the second term "covered government employee", 18 USC 227 uses a different term that does include POTUS:
In this section, the term “covered government person” means— (1) a
Senator or Representative in, or a Delegate or Resident Commissioner
to, the Congress; (2) an employee of either House of Congress; or (3)
the President, Vice President, an employee of the United States Postal
Service or the Postal Regulatory Commission, or any other executive
branch employee (as such term is defined under section 2105 of title
5, United States Code).
That law, btw, says
(a) Whoever, being a covered government person, with the intent to
influence, solely on the basis of partisan political affiliation, an
employment decision or employment practice of any private entity— (1)
takes or withholds, or offers or threatens to take or withhold, an
official act, or (2) influences, or offers or threatens to influence,
the official act of another, shall be fined under this title or
imprisoned for not more than 15 years, or both, and may be
disqualified from holding any office of honor, trust, or profit under
the United States.
This law applies to POTUS, not Kodak Black. And the scope of the law is limited to influencing employment decisions of a private entity – so this law is not applicable.
What SCOTUS would have to rule on is how to interpret the lack of definition w.r.t. §201. There is a book by William Eskridge which discusses the many legal canons that could be used to decide the question. You can also read this summary of law relevant to presidential bribery. As indicated in the subsection on the DoJ's interpretation of the law, it's not a difficult stretch to conclude that POTUS is capable of being bribed, but that's not really the final word on the matter, since that conclusion is influenced by the fact that bribery is constitutionally enumerated as a high crime triggering impeachment. What would matter here is whether POTUS is statutorily an employee w.r.t. §201, a prerequisite for a charge of attempting to bribe.
I.e. we don't know.
