SPRINGFIELD, Ill. (AP) — Half-a-dozen state representatives have sued the Illinois comptroller for holding up their paychecks during the state budget mess.

The Democratic lawmakers filed a lawsuit in Cook County Circuit Court on Friday demanding that Republican Comptroller Leslie Munger and Gov. Bruce Rauner “end unwarranted political pressure.”

In April, Munger began putting paychecks for the governor and lawmakers in line and pays them like other vendors’ overdue bills get paid.

The lawsuit was filed by Democratic representatives Emanuel “Chris” Welch of Hillside, Kate Cloonen of Kankakee, Lisa Hernandez of Cicero along with Chicagoans Mary Flowers, Sonya Harper and Silvan Tabares (tuh-BAH’-riss).

Lawmakers haven’t been paid since May and say Munger Is violating the state Constitution by interfering in a separate branch of government.

Munger was appointed in 2014 to fill a vacancy but lost election last month to Democrat Susana Mendoza. Mendoza has pledge to continue withholding pay.

Munger says lawmakers suing her to get back pay are “cowards.”
