(1) The Attorney General may, when directed to do so by the Governor, take full charge of any investigation or prosecution of violation of law in which the circuit court has jurisdiction. (2) When acting under this section, the Attorney General shall have all the powers of a district attorney, including the power to issue or cause to be issued subpoenas or other process. The Attorney General may, when the Attorney General considers the public interest requires, with or without the concurrence of the district attorney, direct the county grand jury to convene for the investigation and consideration of such matters of a criminal nature as the Attorney General desires to submit to it. The Attorney General may take full charge of the presentation of such matters to the grand jury, issue subpoenas, prepare indictments, and do all other things incident thereto to the same extent as the district attorney may do. (3) All costs, fees and other expense shall be paid by the county in which the investigation takes place, to the same extent as if conducted by the district attorney of that county. (4) The power conferred by this section, ORS 180.060, 180.220 or 180.240 does not deprive the district attorneys of any of their authority, or relieve them from any of their duties to prosecute criminal violations of law and advise the officers of the counties composing their districts.
