There were actually many judges involved in this case. Not just Clinton Judge Donald M. Middlebrooks noted above. Five judges have participated in President Trump’s RICO case so far.
It’s important to note that the day before Reinhart recused himself (June 21, 2022), The president’s counsel filed an amended complaint. The original complaint was entered in March 2022; the amended complaint almost doubled the number of facts asserted in evidence. Many of the claims of facts in the amended complaint came from John Durham’s court filings (which made it difficult for the plaintiffs to deny their validity).
It was after Trump’s second filing that the exodus of magistrate judges began. Following the filing of the amended complaint was a request from the U.S. Department of Justice (“United States”) to substitute itself as a defendant for five of the original defendants: Comey, McCabe, Strzok, (Lisa) Page, and Clinesmith.
On the same day, August 4, 2022, President Trump’s team filed an opposition against Hillary Clinton’s earlier motion to dismiss the RICO complaint (Clinton claimed the president failed to state a claim). His counsel also answered in opposition to motions to dismiss four other defendants.
The clustering of these events is significant because the warrant for the Mar-a-Lago raid was requested/issued on the next day, August 5, 2022.
