“While it’s necessary to proceed with caution due to economic uncertainty, it’s also time to begin the conversation on tax reform that’s beneficial for families and businesses alike,” Kelly said in a statement.

Morris, a moderate Hugoton Republican, served 20 years in the Senate and was president from 2005 through 2012. He lost his Senate seat in a primary-election purge of GOP moderates in 2012 engineered by then-GOP Gov. Sam Brownback’s conservative allies. Brownback had championed slashing income taxes as a potential economic stimulus, and Morris was wary.

Morris has maintained that Brownback persuaded him to save a 2012 bill making deep tax cuts by promising it would be rewritten later, but it wasn’t. Persistent budget problems followed the tax cuts, and Brownback and his allies later blamed Morris, arguing that he and other moderates wouldn’t negotiate better legislation.

Senate President Susan Wagle, a conservative Wichita Republican who rose to the chamber’s top position after the 2012 election, said it’s not a surprise that Morris is “participating in crafting Democratic tax policy.”

“We are seeing the same old Democratic policies that force families to flee in search of a more affordable place to live,” Wagle said.

Morris did not return a telephone message seeking comment Thursday.

Voters came to view Brownback’s tax-cutting experiment as a failure. Bipartisan supermajorities in the Legislature repealed most of them in 2017 over Brownback’s veto, and Kelly ran for governor largely against Brownback’s legacy.

Kelly said Morris will lead the council with another former state senator, Janis Lee, a Kensington Democrat. Lee served in the Senate for 22 years and was influential in tax debates before serving as the chief hearing officer for a special state court that reviewed tax disputes.
