Well, the best thing you could do is to face the fact that you lied and cheated, now on one hand that might be considered a bad thing, on the other remember where you live and remember that what you have done only qualifies you to enter politics on a very low level. My advice would be to march right into that room and tell those ungreatfull pencil pushers that you resent their accusations, that you are only coming before them as a gesture of your good nature and to enlighten them as to what really happened.
Tell them that you had helped the person who owned the original draft, that this person pestered you endlessly day after day, with re-write after rewrite. You would mention her name, however, you are above that sort of finger pointing.
Tell them it got to the point that your desk was covered with her Euro-Trash ideas and when at last you helped him finish it, you were so tired that when at long last you were able to return to your own paper, after a few hours of helping out at the Save The Children's relief effort. Not forgetting to mention that you had to stop off at the blood clinic first to donate, that by the time you sat back at your desk you had misstakenly picked up some of that poor souls paper work and it was accidently incorporated into your own work. Adding; "Had you known that the events that unfolded in the way they did, that you of course would have brought this to their attention much eariler."
Finally closing with "Your only reason even at this late stage for approaching this distinguished pannel is that you have already signed up for an internship with former President, William Jefferson Clinton's office in Harlem, NYC, to devote 3 years to giving legal aid to those most needing of it, those poor people that ask only for a hand up, not a hand out. Remind them that as a child as your father ran off with the lady that was selling vacuum cleaners door to door, you vowed to your dying Mama on her death bed that you would look after your 7 brother and sisters and make sure that they all received a good education, inspite of their handicaps from birth.
For God's sake don't forget to shed a few tears at this point and then turn and start walking towards the door adding "I submit my future and theirs to you good people, I'll just wait outside until you decide what you wish to do..."
Now sunshine, if you follw this advice and pull this off, you are ready for a life time in the Congress of the United States of America! God Bless you boy and good luck!
