Help with WH press corp response to Obama and Clinton

Okay, I need a little help from some of you knowledgeable folks...

I received a forwarded email from a Republican friend about Sarah Sanders being named FrontPage Mag's person of the year for her role in the media wars, i.e., standing up to the press. The implication seems to be that the press has been overly aggressive and partisan.

As far as I've been able to tell over the years, the press asks tough questions. That's their role. And they do it with everyone. So I'm looking for instances (documented instances) where the WH press corps was "equally aggressive" with previous presidents, especially the Democrats. I don't know if there's anything out there, but I want to say "something" to my friend about it.

And please... no comments about being friends with a Republican. We go back a long way before we had any interest in politics.
