Former New York City Police Commissioner Bernard Kerik is beginning what could be a triathlon of federal trials.
Jury selection starts Tuesday in a corruption case that claims Kerik accepted renovations to his Bronx co-op in exchange for vouching for a company that wanted to do business with the city.
The 54-year-old Kerik has pleaded not guilty.
A second trial, on tax charges, and a third, in Washington accuses him of allegedly lying to White House officials vetting him for the Homeland Security secretary post in 2004.
Kerik's defense is barred from making specific references to the 9/11 terror attack that made Kerik a national figure and brought him glowing reviews. The judge ruled last month that the attack was irrelevant to the case.
However, Judge Robinson said defense lawyers may mention that Kerik was commissioner in 2001 and that he received much attention.
It's not known if Kerik or former Mayor Rudy Giuliani, his mentor, will testify.
Kerik is also accused of leveraging his job as New York City's top cop to get $165,000 in renovations to his Bronx apartment from a mob-linked contractor who wanted city contracts. If convicted, Kerik faces up to 20 years in prison.
