The two videos down the page are the 1st and 2nd half a the 20-minute long phone call between Gov. Walker and "David Koch", actually Ian Murphy of the ever-offensive Beast.
The call is very recent, probably from yesterday, as evidenced by its subject matter.
When "Koch" proposes "planting some troublemakers" among the Wisconsin protesters, Walker says "we thought about that". Not to mention that Walker agrees with "Koch" that Mika Brzezinski is "a real piece of ass."
