Didn't Conrad Murray say that he hadn't given MJ Propofal in the beginning?

So he is a liar then. The truth is all coming out on him now. He pumped MJ with 3 or 4 different drugs including Propofal within an hour or so! I just saw it on Nightline. MJ wouldn't go to sleep, so he just kept pumping him with different drugs. Drugs that should never be mixed together one doctor said. And he admitted that he was "trying to ween MJ off the Propofal, so I gave him smaller doses". He's done! He can kiss his doctor's career goodbye.
