PHILADELPHIA (AP) — An investigation into Pennsylvania public officials accused of improperly accepting cash or gifts from a lobbyist is about to produce more charges.

Philadelphia District Attorney Seth Williams plans to announce charges against three people at a news conference Tuesday in the city.

Two are described as current state lawmakers and the third as a former state legislator.

Williams will be joined by members of his public corruption task force, as well as by the state police.

Two current Democratic state representatives from Philadelphia, Ron Waters and Vanessa Lowery Brown, were charged by Williams’ office in December with bribery, conspiracy and other offenses. They have waived a preliminary hearing.

A former Philadelphia Traffic Court judge, Thomasine Tynes, pleaded guilty three months ago to conflict of interest as part of the same investigation.

Williams revived the case in June after The Philadelphia Inquirer reported that Attorney General Kathleen Kane had shut it down, deeming it to be too flawed to win convictions in court.
