“Issa screwed up these investigations about as bad as anyone possibly could.”
Yes, he did by letting Lerner off the hook.
I’m reading it differently. Issa may be collecting all the evidence he can find against Lerner before he brings her back.
When he’s ready he’ll present it to her with an option of talk or LOOOOOOng jail time. If she is willing to testify against the correct person then they can deal otherwise she’ll wear orange.
In the mean time bet she’s not sleeping very well and if she a drinker seldom sober.
