So I'm not sure how much actual fallout there will be from this aside from Hannity possibly violating some disclosure protocol with Fox and making himself look like a shady ****, though this possibly places him under new legal scrutiny since, as Hannity put it, "Michael Cohen has never represented me in any matter. I never retained him, received an invoice, or paid legal fees. I have occasionally had brief discussions with him about legal questions about which I wanted his input and perspective."
If Hannity's version of their relationship is true, it means that his and Cohen's communications are not covered by attorney-client privileged and Hannity could possibly get nailed for even minor bullshit.
If Cohen's version is more accurate; that Hannity was an actual client, then it makes Hannity's taint-licking and brown nosing even more hilarious.
I'd post a link, but if you just slam "Cohen Hannity" into any search engine ever you'll get a shitzillion results.
