I highly doubt anything will happen with Gregory but as I posted before, he's been in trouble before with the NBC News mgmt about how he does things on Meet the Press.
He reminds me of the dreadful character Jeff Daniels plays on HBO's drama about broadcast news. If you have HBO or have seen any episodes, then you know how anti-gun & slanted it can get. I got very annoyed when the Daniels character(a Glenn Beck/Bill O'Reily type) "disarms" another female character of a Walther PPK .380acp. He then scolds the woman, telling her that most armed citizens in real critical incidents have their guns snatched by the subject(s). REALLY? Huh. With all the 1000s of new concealed carry licenses & new state laws, you'd think weapon retention or gun thefts would be a HUGE media issue.
