Using the Ihub streamer, I don't see a 1.2 million buy at the close, but I have noticed closing differences reported between Ameritrade and IHUB very often as the block trades can be broken down into smaller blocks.
There was a 871,729 block listed on the IHUB. It is hard to pin point the reason behind it; Institutional Holder picking some up, or a Hedge Fund buying to cover with a large block to reach the desired level of trades for the day which is good for several reasons.
It was not a t-trade so it was not a manipulated trade reported late, but a straight, over the counter block buy.
