Bob Onder

Onder was an outspoken supporter of HB 1562, a bill that expanded the crime of sex trafficking to include the advertisement of minors for prostitution or pornography.

Onder is anti-abortion, he was the original author of legislation that requires annual, unannounced state inspections of healthcare clinics that provide reproductive healthcare; bars clinics from instructing ambulances to silence their sirens or turn their lights off; mandates that pathologists test fetal tissue; enacts whistleblower protections for employees of abortion clinics; and exempts pregnancy resource centers from a St. Louis ordinance barring discrimination over reproductive choices.

Onder's bill received a few significant changes, such as changing the pathologist deadline from 24 hours to five days, and became Senate Bill 5, with a new sponsor in Senator Andrew Koenig.

The bill was strengthened and passed by the Missouri House of Representatives, then passed by a vote of 22-9 in the Missouri Senate and signed by Governor Eric Greitens.

Onder previously was a member of the Missouri House of Representatives from 2007 to 2008.

Onder served a single term in the Missouri House of Representatives from 2007 to 2008, having been elected in 2006.

In 2008, Onder left the state legislature to run for the US House in Missouri's 9th congressional district, where incumbent Kenny Hulshof was not seeking re-election.

Onder distinguished himself as one of the more fiscally conservative candidates, emphasizing his free-market voting record in the Missouri House and earning the endorsement of the Club for Growth.

Onder ultimately lost the Republican primary election to Blaine Luetkemeyer.

In 2008, Onder authored and sponsored HB 1549, a piece of legislation targeting undocumented persons.

The bill forbade the creation of sanctuary cities in Missouri, allowed for cancellation of state contracts for contractors if they hired undocumented persons, and required public agencies to verify the legal status of immigrants before providing social service benefits.

Additionally the bill criminalized the transportation of immigrants for exploitative purposes.

The bill passed the State House and Senate with strong support and was signed into law by Matt Blunt.

Onder also sponsored legislation that would have strengthened Missouri's informed consent before abortion statute, including requiring abortion clinics to allow pregnant people the opportunity to view an ultrasound of the fetus.

The bill also would have criminalized coercing a woman to have an abortion through abuse, violence or threats.

The bill passed the State House by a vote of 112-33 but died after a filibuster in the State Senate.

In his first year in the Senate, Onder was elected to Senate leadership as Assistant Majority Floor Leader.

In 2014, Onder ran for the Missouri Senate in the 2nd district, defeating Chuck Gatschenberger and Vicki Schneider in the Republican primary.

No Democrats ran for the seat, so this primary victory was tantamount to election.

He was elected Assistant Majority Floor Leader in 2015.

In 2016, Onder attended the 2016 Republican National Convention after his selection as a Trump delegate as part of the Missouri delegation.

Onder was a founding member of the Missouri Senate's Conservative Caucus.

In 2016, Onder introduced Senate Joint Resolution 39, a proposed amendment to the Missouri Constitution that would protect wedding industry businesses that refuse to serve LGBTQIA+ couples.

This bill passed the Senate over a Democratic filibuster, but failed to make it out of committee in the House.

In 2017 he became the Chairman of the General Laws Committee.

Additionally, he serves as Vice-Chairman of the Committee on Judiciary and Civil and Criminal Jurisprudence.
