TOPEKA, Kan. (AP) — Kansas Gov. Sam Brownback isn’t publicly ruling out any ideas for helping to close state budget shortfalls.

That’s left officials and lawmakers to speculate about the proposals he’s expected to roll out before the Legislature convenes again Jan. 12.

The Republican governor’s administration is working on a plan to close combined shortfalls of more than $700 million in the current and next state budgets.

A few GOP legislators have talked about diverting money set aside for big highway projects or backtracking on aggressive personal income tax cuts enacted at Brownback’s urging in 2012 and 2013 in an effort to stimulate the economy.

The budget problems also could jeopardize increased funding for public employee pensions aimed at stabilizing the long-term health of the retirement system for teachers and government workers.
