[For more, see NewsBusters.] ABC journalist Jon Karl dared to push Barack Obama on his use of executive power, demanding to know if the commander-in-chief is an "imperial president." But Karl's own network ignored the question, declining to air it on Wednesday's World News and Nightline or on Thursday's Good Morning America. It wasn't until the little-watched America This Morning, a program that airs at 4am on ABC, that the question came up. At the August 6 news conference, Karl pointed out: "When you were running for president you said, quote, 'The biggest problems we're facing right now have to do with George Bush trying to bring more and more power into the executive branch and not go through Congress at all and that's what I intend to reverse.'"
