I think it's clear we're still in the rumor and assumption phase (about the nomination).
Don't agree. With a new administion, there are a lot of nominated positions they have to go to Congress before confirmed. Potential nominees are carefully vetted, but despite best advisors opinions on public response and background checks (illegal aliens as housekeepers, etc.), they "float" names so press will do just what they're doing
here. Press does it's own vetting and opinionating and public is pulsed for their response. Last thing they want is a prolonged or controversial confirmation hearing by Senate or someone from the past coming out with adverse info that was missed.
I did find it interesting that General Shelton didn't recommend him for the Army (his service). Would mean more to hear from former SECNAV (like Lehman) or high ranking Navy admiral.
