"I'm concerned that he doesn't have the qualifications or independence needed to lead this important branch of government," she says.
Grassley also said he had DAG Rod Rosenstein explain to Durbin why DOJ won't confirm if it's investigating Alfa Bank.
Says Comey "recently came under fire for doing this very thing."
He says he's worried Benczkowski will be "a backchannel source of information from this Special Counsel investigation to the recused Atty General."
Calls DOJ's letter replying to his questions "ridiculous."
Whitehouse: B/c head of National Security Division has access to probe (for good reason), so it's not unreasonable to think head of Criminal Division might participate too.
Feinstein responds that Benczkowski "repeatedly refused" to promise that he'd recuse from the Russia probe if confirmed.
Nonetheless, he says, Benczkowski has "no experience" in prosecution or criminal defense work, and he's too close to the recused AG.
"What happened between the Alfa Bank pinging into the Trump campaign during the campaign? I don't know the answer."
"I want [DOJ nominees] to at least know what the heck they're doing, and [Benczkowski has] shown that he doesn't have that kind of judgment."
