ST. ALBANS, VT. >> A Vermont state senator is scheduled to go on trial this week on sex charges.

Sen. Norm McAllister was arrested in May 2015 outside the Statehouse and arraigned on three counts of felony sexual assault and three counts of misdemeanor prohibited acts. In January, senators voted to suspend him.

The Franklin County Republican has maintained his innocence, and filed nominating petitions last month to seek re-election to the Senate.

Several lawmakers are potential witnesses, including two who had shared a rented house with McAllister in Montpelier during the 2015 session.

One of McAllister's alleged victims worked with him as an assistant at the Statehouse during that session.
