The Michigan attorney general's investigation into interference in the 2020 election has led to charges against 15 Republicans who acted as fake electors for Mr. Trump. The investigation remains open, with names like Trump, Meadows, and Giuliani being mentioned. Similar investigations are ongoing in other swing states. Trump also faces federal cases for election interference. The focus is on states crucial in deciding the presidency. The involvement of others besides the fake electors is being questioned. The presiding judge has divided pretrial hearings due to the number of defendants, with the case's future undecided.
