The first is a timeline waypoint in relation to "muh Russia"
And very early in Trump's tenure, he fired then-acting attorney general Sally Yates [January 30], a holdover from the Obama administration while Sessions wasn't yet confirmed. At that point, the scope of the Russia investigation and its focus on the Trump team wasn't well known ...
The second involves the supposed reason for Sessions' to recuse.
Sessions wouldn't have even known there was reason to recuse himself when he was nominated, given his recusal had to do with his failure to report contacts with Russia's ambassador during the ensuing confirmation process.
From Washington Compost:
“Sessions wouldn’t have even known there was reason to recuse himself when he was nominated, given his recusal had to do with his failure to report contacts with Russia’s ambassador during the ensuing confirmation process.”
Trump’s using an old leadership trick — put the monkey on the other guy’s back.
If Sessions had to recuse, that’s HIS problem, not Trump’s. If Sessions can’t do his job, that’s the bottom line.
