On the latest episode of Politically Speaking, St. Louis Public Radio’s Jason Rosenbaum and Sarah Kellogg dive into the major fissures among Senate Republicans that were showcased during last week’s veto session dispute.

In addition to breaking down what happened on the Senate floor, Rosenbaum and Kellogg spoke with two senators who were on opposite sides of the often pointed debate: Bob Onder, R-Lake Saint Louis, and Majority Leader Caleb Rowden, R-Columbia.

Here’s what was discussed on the show:

• Kellogg explained the origins of the legislative fight, which revolved around whether a senator who was not the sponsor of a bill could make an override motion. Sen. Mike Moon, R-Ash Grove, sought to override Parson’s veto of a line item of tax refunds for certain businesses, but he initially was prevented from doing so by Lt. Gov. Mike Kehoe, who was presiding.
• Both Onder and Rowden delved into whether it was appropriate for Kehoe to not recognize Moon for the motion, especially since it’s relatively rare for a presiding officer to make such a move.
• The two senators discussed whether the tensions will spill over into the 2022 legislative session. Before last Wednesday, some conservative members of the Senate were openly criticizing the chamber’s leadership on a host of issues — including how they went about passing a gas tax hike and a renewal of a critical tax to fund Missouri’s Medicaid program.

Onder has been in the Missouri Senate since 2015. He previously served a single term in the Missouri House before making a run for the now-defunct 9th Congressional District seat. Onder is a doctor who also obtained a law degree. He represents portions of St. Charles County.

Rowden recently won reelection to Missouri’s 19th Senate District, which takes in Boone and Cooper counties. He first won election to that seat in 2016 after serving two terms in the Missouri House. As majority leader, Rowden controls what gets debated on the floor — making him one of the most powerful legislators in Jefferson City.
