As a concerned citizen this looks good though I personally think a special counsel with no partisan bias involved anywhere and the ability to file criminal charges would be the best option. And probably best not to involve the AG too much in the process.
I'm more than open to being persuaded on removing myself from the process through amendments, sure.
I think as good way to do it would be to insert in the legislation that you can review it for security concerns but are expressly forbidden from changing or obstructing the substance of it. You can have a role in making sure it doesn't endanger national security but you have to allow the investigation and report to otherwise go ahead as is.
