Disgraced former Police Commissioner Bernard Kerik appeared in court Wednesday for a second day of testimony at a perjury trial in the Bronx.
Kerik took the stand Wednesday in the case against Peter and Frank Ditommaso.
He denied having a shady business relationship with the brothers, who are accused of lying to a grand jury about lavish renovations on Kerik's Riverdale apartment.
The former police commissioner said he paid the brothers $30,000 to do the work.
Prosecutors are trying to prove the Ditomassos may have done extra work for free as part of a political favor.
This week marks the first time Kerik made a public appearance since pleading guilty in 2010 to filing false tax returns on those renovations and eight other felonies.
He's serving four years in a federal prison.
