The grand jury investigating Gov. Rick Perry returned to work Friday. Four of Perry’s top aides headed into the grand jury room through the public entrance, despite a request to enter through a private door. The aides included spokesman Rich Parsons, general counsel Mary Anne Wiley, and deputy chief of staff Mike Morrissey.

The grand jury is investigating whether Perry illegally withheld money from the Travis County District Attorney’s office. Perry vetoed funding last year for the public integrity unit, which is overseen by the District Attorney’s office. Perry had threatened to slash the funding if DA Rosemary Lehmberg refused to step down after a drunk driving arrest. He followed through with that threat when she refused.

It is not clear when Perry will testify and his aides did not comment Friday.
