Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (15:00): As members of parliament we are all responsible for our own actions and for those actions in terms of the way in which we engage. In relation to the member for Dawson, it is well known that the member for Dawson is a vocal participant in public debate. I again draw the distinction between the comments that Senator Keneally alleges have been posted—of course, I'm sure on nearly all of our different social media platforms we have had cause at times to delete comments that've been made that are completely inappropriate and that deserve condemnation. I would urge all of us, including the member for Dawson, to be so vigilant in doing so. I ask that further questions be placed on the Notice Paper.
