Okay.
To summarize your testimony, you were given two options. You knew that Deloitte was behind one of the options. You did not know that GC Strategies was behind the other. You chose the option that involved a company that you weren't aware of. You don't know who made the decision regarding GC Strategies. You at no point heard from or consulted with your bosses within the department. Mr. MacDonald fully fabricated significant aspects of your conversation with him.
I find that testimony quite unbelievable, frankly, but that's what you have to say.
