This is dictated by the Arizona Constitution. Article IV, Section 2, Part 3 reads: “The sessions of the legislature shall be held annually at the capitol of the state, and shall commence on the second Monday of January of each year.”
That puts the session start for 2020 on Jan. 13.
Gilbert is represented by two Legislative districts. District 17 is mostly Chandler, but it hits a portion of the west side of town—particularly in the Northwest. LD17’s senator is J.D. Mesnard, a Republican. Its representatives are Republican Jeff Weninger and Democrat Jennifer Pawlik.
The remaining, and far larger, part of town is in District 12. All the legislators there are Republicans: Eddie Farnsworth in the Senate, and Warren Petersen and Travis Grantham in the House.
