The Washington Post first reported last night that he had been considering pardoning Johnson.
The details: Johnson's cause was championed last week at the White House by Kim Kardashian West. White House senior adviser Jared Kushner, who pushed for Johnson's pardon, had been in contact with Kardashian West over the past several months on the issue. Per a source familiar, White House counsel Don McGahn is skeptical of the merits of pardoning Johnson.
The big picture: This is part of a broader effort led by Jared Kushner to highlight the issue of prison reform — particularly focused on nonviolent offenders.
More about Johnson's crime, per Mic, who first reported on Kardashian West's conversations with Kushner: "Johnson was convicted and sentenced to life without parole in 1996 for her role facilitating communications in a cocaine trafficking operation in Memphis, Tennessee."
