The attorney for Michael Jackson's doctor, Conrad Murray, today aggressively contested media reports -- based on a leaked witness report -- that Murray attempted to hide evidence and delayed calling 911 as Jackson lay dying and said investigators rushed to implicate Murray in the star's death.

"It's just a bald-faced lie," Ed Chernoff said in an exclusive interview with "Good Morning America" that aired today. "[The] doctor called 911 as soon as he could… Let me just say, unequivocally, he did not – he was not cleaning up any bottles… The scene was not consistent with anyone trying to clean something up."

Chernoff said Murray did not immediately call 911 because there was no house phone in the room where Jackson was and he could not leave his patient to make the call.

Murray stands accused of administering the lethal dose of a powerful sedative that killed the pop superstar. He pleaded not guilty to manslaughter in February.

Chernoff said his client isn't responsible for the star's death, and that police rushed to blame someone.
