Senator WILLIAMS (New South Wales—Nationals Whip in the Senate) (16:28): Deputy President, I have a point of order. Earlier on Senator Di Natale sought leave to speak for one minute. I was in my office watching and, during that time, he referred to 'where both of these clowns get most of their material from', referring to senators in this place. You ruled there was no point of order. I'm asking you to revisit that decision. I believe it is unparliamentary for a senator to refer to others in here as 'clowns'. I ask you to ask that Senator Di Natale withdraw those comments. The DEPUTY PRESIDENT: Senator Williams, I will check whether you can actually raise a point of order after the event. They are usually taken at the time. I stand by the ruling I made at the time.
