Prosecutor Chris Niewoehner is questioning Monk about a 2004 meeting during a fund-raising trip to Los Angeles.
Rod Blagojevich, Lon Monk, Tony Rezko and Chris Kelly -- along with the then-governor's security detail, scheduler, scheduler's daughter and several of Rezko's associates -- boarded a private plane on Jan. 22 and stayed at the Regent Beverly Wilshire Hotel.
The trip provided a chance to meet privately with "fewer distractions than we'd usually have, since we were out of state," Monk said.
Rezko led the meeting, Monk said, elaborating on the money-making schemes they had discussed at the Rezmar meeting.
Again, Rezko wrote up the plans for each way to make money and put a dollar figure next to each one of them, Monk said.
"What did you do?" Niewoehner asked him.
"Listened," Monk said.
Rezko and Kelly didn't ask him or Blagojevich to do anything during the meeting, Monk said, but it was implied that they would have to "cause the state to do something to bring a number of these ideas to fruition" down the line.
Again, Monk said, the plan was that he would get his quarter of the money after Blagojevich was out of office.
"We didn't want to be getting the money when Rod was in office when there was a lot of scrutiny" from law enforcement and the media.
