I was watching Howard Kurtz's "Reliable Sources" this morning and he stated that Fox News made no mention of the prank call that exposed Scott Walker.
So I googled it:
This is on their website so I am not sure if it WAS mentioned on TV.

The Buffalo Beast blogger who prank-called Wisconsin Republican Gov. Scott Walker, falsely posing as billionaire David Koch, has written some edgy - some may say offensive - articles in the past. For the publication he edits, Ian Murphy has written such pieces as "F*** The Troops," a dissertation explaining why he thinks, "the nearly two-thirds of us who know this war is bullshit need to stop sucking off the troops," and "Let There Be Retards," an exclusive look inside a Kentucky creationism museum - while Murphy was falsely pretending to have Asperger's Syndrome.
