Probably because after campaigning on a promise to "lock her up!" right after being sworn in Trump said there would be no investigation or prosecution of the Clintons! By failing to go after the Clinton's like he promised, he opened the door for the Democrats to go after him on Russia!

So now Trump is passing blame on to Jeff Sessions when it was his own orders that DOJ not investigate or prosecute Hillary Clinton.

While Trump clearly regrets that mistake now, blaming Jeff Sessions for his own leadership mistakes is low and below the belt.
