Honourable senators, for all of these reasons, and I have canvassed but a few, I feel it is our duty to urge that this bill be referred back to the committee so that the committee can examine three or four further witnesses - publishers, the advertisers, a few constitutional lawyers and a cost analyst, in terms of the publishing fund.

Based on that paragraph can we conclude that this sentence is true?
One of the witnesses would be an advertiser
