HARRISBURG — The second prosecution witness was still on the stand Friday as the second week of the public corruption trial of a former Pennsylvania state lawmaker and three of his aides drew to a close.

Jeff Foreman, who was chief of staff to defendant Mike Veon until the Beaver County Democrat lost re-election in 2006, has spent two days telling jurors what he knows about the alleged use of the General Assembly's employees, equipment and cash to wage campaigns.

Foreman admitted that he knew he was engaging in illegal campaign practices during the nearly two decades he spent working for the Legislature. He and six others pleaded guilty last month to related charges and are cooperating with the prosecution.

Veon defense attorney Dan Raynak focused many of his questions on the timing of statements Foreman provided to the attorney general's office since his Jan. 6 guilty plea to four felonies. The newest information implicates Veon and others and has formed an important component of the case the prosecution has so far put forward.

Much of Foreman's testimony Friday involved the many emails that prosecutors have introduced as evidence — some that jurors have already been shown several times.

Lawyers from both sides expressed some frustration with the pace of the trial after court Friday. Dauphin County Judge Richard Lewis has scheduled a session on Presidents Day and said the trial might also continue on Saturdays.

Prosecutors have said they plan to call 20 to 30 witnesses, and all four defendants also may put on their own cases, suggesting the trial could go on far longer than the month that had been projected.

Veon served as the No. 2 ranking House Democrat before he lost re-election in the pay raise backlash election more than three years ago.

He and his former aides Brett Cott, Steve Keefer and Annamarie Perretta-Rosepink are on trial for theft, conspiracy and conflict of interest charges.
