HARRISBURG — The four defendants in the Harrisburg legislative corruption trial wrapped up their case Wednesday without taking the stand, and jurors will soon begin deliberations in a proceeding that already has stretched on for nearly six weeks.

Mike Veon, Steve Keefer, Annamarie Perretta-Rosepink and Brett Cott each could face lengthy jail sentences if jurors are persuaded by the attorney general's office's charge that they conspired to siphon taxpayer-paid computer services, employee time and other resources to wage partisan political campaigns.

The defendants face various counts of theft, conspiracy and conflict of interest. Veon alone has 59 charges.

Cott's attorney, Bryan Walk, said he felt there was no need to put his client on the stand. Walk cited Cott's use of e-mails to send campaign ideas to his co-workers as the type of minimal infraction that is meaningless in terms of a crime.

"Did he do campaigning?" Walk said. "Absolutely. The commonwealth wants to mislead this jury throughout to say if anybody did campaign work, they're wrong. And that couldn't be farther from the truth."
