A headline in the local paper stated that the Health Canada scientists, who you had mentioned earlier in your speech had taken affidavits in order to be able to talk, had been gagged by the department over their protest and will likely be under gag order for the rest of their careers, despite a Senate promise to keep an eye on Health Canada's management problems.

Based on that paragraph can we conclude that this sentence is true?
Health Canada scientists cannot talk about their work.
