This has been public info for years, which is why Sessions’ failure to act was such an over-the-top outrageous abdication of duty that he should be considered a co-conspirator when a proper AG finally starts prosecuting these crimes.
Sessions is/was a high treason co-conspirator. His pick of rotten rod as his DAG, his recusal, and the subsequent appointment of the mueller coup did not happen by chance. It was orchestrated well in advance.
