As reported by Ralph Blumenthal at the NYT, published Feb 20:
"The operator of an activist Republican Web site and news service said Friday night that he had known for two years that his White House correspondent went by two identities."
And golly gee, it didn't strike Eberle as strange! And golly gee, he didn't know about Gannon's other goings on and if he had he doesn't think he would have brought him on. By and large the article is really pretty softball stuff, but it's interesting to read what Eberle says regarding what he did and did not know about Gannon.
