Justice Dept. criminal probe into fake electors

I hope that's it's more than just another empty promise. And why isn't Twitler himself included in the probe, since we've already seen evidence that he was directly involved?* The headline from Democracy Now: 

"The Justice Department has stepped up its criminal investigation into the creation of fake slates of pro-Trump electors looking to overturn Joe Biden’s presidential victory in 2020. That’s according to The New York Times, which reports the probe has a particular focus on the team of lawyers that worked on behalf of Trump, including John Eastman and Rudy Giuliani."

*From the NYT report: "In March, a federal judge in California ruled in a civil case that Mr. Eastman had most likely conspired with Mr. Trump to obstruct Congress and defraud the United States by helping to devise and promote the alternate elector scheme, and by presenting plans to Mr. Pence suggesting that he could exercise his discretion over which slates of electors to accept or reject at the Jan. 6 congressional certification of votes."

"Ms. Ellis had assisted Mr. Trump in an 'unsuccessful and potentially criminal effort' to stave off defeat by writing two memos arguing that Mr. Pence could ignore the electoral votes in key swing states that had pledged their support to Mr. Biden."
