The NAACP has now filed a lawsuit against Trump and his campaign at the United States District Court for the District of Columbia:

In this case, it is thus Trump who is the accused of electoral fraud, not the accuser.
The core of the complaint is that attempting to block certification of the vote in Michigan is a violation of section 11(b) in the Voting Rights Act - and an attempt to disenfranchise black voters by specifically targeting areas with a high percentage of black voters:
Voting Rights Act/52 U.S. Code § 10101 wrote:
(b) Intimidation, threats, or coercion
No person, whether acting under color of law or otherwise, shall intimidate, threaten, coerce, or attempt to intimidate, threaten, or coerce any other person for the purpose of interfering with the right of such other person to vote or to vote as he may choose, or of causing such other person to vote for, or not to vote for, any candidate for the office of President, Vice President, presidential elector, Member of the Senate, or Member of the House of Representatives, Delegates or Commissioners from the Territories or possessions, at any general, special, or primary election held solely or in part for the purpose of selecting or electing any such candidate.
