But he would be shocked to hear that his secretary had heard him.
"The only thing I can say to you, Sir, is that if my snorting was so loud that you could hear me snorting through a wall and a door, then I'm amazed at the loudness of my snorting," Levine told Rezko's chief defense counsel Duffy.
But in a ruling issued before the start of the trial, U.S. District Judge Amy J. St. Eve said office workers had heard snorting sounds coming from Levine's inner office and found bloody tissues. He admitted on the stand Monday that he got nosebleeds from ingesting as many as 10 "lines" of powdered drugs a night into his nose through a straw.
Rezko, 52, is charged with scheming with Levine to get kickbacks from money management firms wanting to invest assets of the $40 billion fund that pays the pensions of retired downstate and suburban teachers.
Rezko also is charged with scheming with Levine to split a $1 million bribe from a contractor who wanted to build a hospital in Crystal Lake.
Levine sat on the two state boards with control over such matters. But prosecutors say it was the more than $1 million Rezko raised for Gov. Rod Blagojevich's campaign fund that gave him the clout to launch the schemes. Blagojevich has not been charged with any wrongdoing.
Rezko denies he took part in any such schemes. But Levine has pleaded guilty and is testifying as the government's key witness in hopes of getting a lenient 67-month federal prison term.
Duffy maintains Levine's brain was so badly cooked by years of taking various powerful drugs that he doesn't recall just what happened.
The veteran defense attorney, a former federal prosecutor, walked a careful line Monday as he questioned Levine.
Duffy is allowed to ask Levine about his drug use, but is barred by a court order from asking about what prosecutors call Levine's "personal social life" and what defense attorneys have been describing to jurors as his "secret life."
St. Eve ruled telling the jurors exactly what that life consisted of would be too prejudicial to the government's case.
But Duffy repeatedly got Levine to admit that he took part in all-night drug sessions with male companions at various hotels, sometimes in groups and sometimes one on one.
He testified that some of the drug parties started in midmorning and went on through the night and into the next day.
Levine again testified that his favorite drugs before March 2004, when FBI agents knocked on his door and his life abruptly changed, were crystal methamphetamine and kaetamine, a tranquilizer known to users as Special K.
He said he sometimes took as many as 10 lines of each at a party.
Duffy asked him if on the morning after such a party he ever "didn't have a clear recollection of what happened on the night before?"
"I don't believe so," Levine said.
"Did you ever say to your drug buddies, 'What the hell happened? I don't recall what happened?"' Duffy asked.
"I don't recall that," Levine said.
"Is it possible that you don't remember it because you are unable to remember it?" Duffy asked.
Levine answered: "It's possible."The Associated Press contributed to this report.
