As President Trump continues to denigrate Attorney General Jeff Sessions on Twitter, and his allies in Congress lay the groundwork for him to fire Deputy Attorney General Rod Rosenstein, the number-three position at Justice Department has been vacant since Rachel Brand stepped down in February. The official reason given for her departure was that she could not pass up the top legal position at Walmart, but NBC News reported that she told friends she felt “overwhelmed and unsupported” in the job, and feared she would be asked to oversee the Russia investigation.

The Wall Street Journal reported that the Trump administration has put filling the associate attorney general position on the back burner after several candidates expressed similar concerns. Since Sessions has recused himself, if Rosenstein were to do the same oversight of Special Counsel Robert Mueller’s probe would fall to the associate AG. In a Saturday Night Massacre situation, the number-three official could easily wind up as acting attorney general.
