I am sure he just spews the same reasoning and lines he has already used to justify these rules. It might be interesting to see the letter nonetheless. I didn't see anything in the article about his stating anything about how he could/would change the law. There's no info on the DOJ website but I wouldn't expect to see it there. Maybe the NRA will release it. Otherwise, if someone really wanted to see it they could make a FOIA request. Prob not worth it in my opinion.
