In the movie "History of the World, Part I," Mel Brooks, who plays King Louis XVI,  belts out proudly: "It's good to be the king."

For Kwame Kilpatrick, it was good to be king of Detroit.

On the first day of testimony in Kilpatrick's public corruption trial,  IRS agent Ronald Sauer testified how he documented Kilpatrick's banking statements, which showed he magically started making regular cash deposits beyond his paycheck once he became mayor in 2002. Up until then, Kilpatrick did not make cash deposits, but rather withdrew money when he got checks for being a state representative.

Sauer testified that  Kilpatrick made $531,041 cash deposits from 2002 to 2008 while mayor. Additionally, he said Kilpatrick made $282,000 in cash payments to cover credit card debt.

Kilpatrick is charged with taking bribes and kickbacks from contracts. His father Bernard Kilpatrick, his good friend Bobby Ferguson, a contractor, and the former water department boss Victor Mercado are also on trial.

During cross examination of agent Sauer, Kilpatrick's attorney James Thomas tried to suggest that the cash Kilpatrick regularly deposited in the bank may have come from gifts and from Kilpatrick's wife Carlita's income.  

But the agent said that Karlita Kilpatrick only filed income tax formes in 2002 and 2003 and nothing after that. He said her income was less than $100,000 a year.

Later in the morning, Jerome Robinson, an employee at the First Independence Bank in downtown Detroit testified that the Kilpatrick came in with cash payments to pay for credit card debt. He said Kilpatrick also brought cash to buy cashier's checks, one of which was for $9,000 and another for $15,000.

Kilpatrick's attorney Thomas asked him if he realized that the $15,000 cashier's check was made on Oct. 28, 2008, the day that Kilpatrick was heading to jail and needed to make a restitution payment in his state criminal case. Robinson said he did not realize that. 

Still, the question remained, where did the money come from?

Updated: 11:10 a.m. -- J. Diane Dixon, the consuming lending manager at First Independence Bank in downtown Detroit testified that Kilpatrick made many cash payments on a $50,000 loan, and that some were made multiple times on the same day.

Thomas got her to say that it wasn't unusual for people to make cash payments on loans.

11:40 a.m.  -- Detroit Police Sgt. Jefferson Travis, who was second in command of the security detail for Kilpatrick, testified that the mayor went on a private jet on a few occasions to trips in the U.S. including Tallahassee where the mayor had attended college. The jet was owned by businessman Tony Soave, who had contracts with the city, who claims that Kilpatrick extorted money from him. 

He testified that he didn't believe that anything shady was going on between contractor Bobby Ferguson and Kilpatrick, who were close friends. He also said he had no knowledge that there was ever a party at the Manoogian Mansion and he said; "I wouldn't consider him a partier. I don't recall him drinking."

Travis said that he had worked for four different mayors and that he considered Kilpatrick a very hard working one.

12:01 p.m. -- Police Commander Dwayne Love. who served as a sergeant on the mayor's detail, testified that he would make cash deposits at banks for the mayor. He also testified that in 2006, he went with the mayor on a pleasure trip to Bermuda with some other people, including Bobby Ferguson, on a private jet owned by Tony Soave.  He said the trip was designed to unwind, and that the mayor wanted to thank those who helped him get elected. He said he had to pay $500 for the trip and he got a call from chief of staff Christine Beatty telling him to protect the mayor to make sure he stayed safe.

Another time, in December 2006,  as part of his job, he went with the mayor to New York on a private jet owned by Soave. This time Soave was on the trip along with the mayor's chief of staff Christine Beatty. He said Soave, Beatty and Kilpatrick went shopping in the city on the one day trip.  Under cross examination, he said he did not recall the mayor buying a lot of things, or getting any expensive watch from Soave.

He said he was involved in doing sweeps for bugs in the Manoogian Mansion. Asked if he ever was involved in a sweep for bug while he worked for Mayor Dennis Archer for five years, he said no.

12:25 p.m. -- Police Officer Chad Smith, who worked on the mayor's wife's security detail, testified that he was once asked to go to the Manoogian Mansion, and fetch $1,500 from a shoe for a payment at the bank for his credit card debt.  Smith said he was a close friend of Kilpatrick. He said they went to high school together, and last talked at the 20 year class reunion four years ago, but they were still lifelong friends.
