LOS ANGELES — A top executive of the company that was producing Michael Jackson’s “This Is It” tour has acknowledged he negotiated a deal for the doctor that the pop star had chosen to accompany him.

But AEG Live executive Paul Gongaware testified Tuesday he never investigated Dr. Conrad Murray’s background and merely accepted Jackson’s recommendation.

Gongaware testified in the Los Angeles trial as a hostile witness called by lawyers for Jackson’s mother in her negligent-hiring lawsuit.

He came under aggressive examination on whether AEG or Jackson was responsible for hiring Murray, who was ultimately convicted of involuntary manslaughter in the superstar’s death.

Gongaware said the fact that Murray had been Jackson’s personal physician for three years was good enough for him.

Jackson died in 2009 after being given a powerful anesthetic.
