A lifelong farmer and former public school teacher, Hartzler began her career in public service in the Missouri General Assembly, where she served as a state representative for six years, from 1995 to 2001, representing parts of Cass and Johnson counties.

Following her service in the statehouse, Hartzler served as state spokeswoman for the Coalition to Protect Marriage, as well as being appointed chair of the Missouri Women's Council. In 2010, Hartzler returned to politics and was elected to the U.S. House of Representatives, defeating 17-term Democrat Rep. Ike Skelton in the 2010 midterm elections. With her victory, she became the second Republican woman ever elected to Congress from Missouri and the first Republican to represent the district in 55 years. 

While in Congress, Hartzler served on the House Armed Services and Agriculture committees. On the House Armed Services Committee, she served as the chair of the Oversight & Investigations Subcommittee, the ranking member of the Tactical Air and Land Forces Subcommittee, and as a member of the Seapower and Projection Forces Subcommittee.

On the House Agriculture Committee, she served on the Livestock & Foreign Agriculture Subcommittee and the Biotechnology, Horticulture, and Research Subcommittee. She also chaired the House Values Action Team, served as a commissioner of the Congressional-Executive Commission on China, and was appointed to the PREVENTS Task Force for suicide prevention.

Her Congressional achievements include effectively advancing legislation to strengthen the military, protect the border, advocate for veterans, promote family values, combat China, aid Missourians devastated by natural disasters, fight the opioid epidemic, and support Missouri farmers and ranchers. She also helped pass legislation to help Gold Star families.

In 2022, Hartzler ran for the open seat in the United States Senate, vacated by Senator Roy Blunt (R-Mo.). During her campaign, she received the endorsements of Senator Josh Hawley (R-Mo.), Susan 8. Anthony's List, and the Missouri Farm Bureau — the first time in history that the agricultural organization supported a candidate in a contested primary. She came in second in a field of 21 candidates. 

Hartzler lives on a working farm in Harrisonville, Missouri, with her husband, Lowell, and daughter, Tiffany. She graduated from Archie High School as valedictorian of her class, graduated summa cum lade with a Bachelor of Science in education from the University of Missouri, and earned a master's degree in education from the University of Central Missouri.

Hartzler is the author of "Running God's Way," which outlines biblical campaign strategies for Christians running for public office. 

Larry LaRocco, a leader in the intersection of financial services and public policy, brings more than 30 years of experience from the private and government sectors to his professional relationships and strategic counsel assignments.

His career in financial services started in 1973 in Idaho’s banking industry. After six years as a senior staff assistant to a veteran Idaho U.S. senator, LaRocco worked for eight years as an executive in the securities sector with Shearson Lehman Hutton and Piper Jaffray. He left the securities business in 1991 to begin his service in Congress.

LaRocco is a former Democratic Member of Congress who represented the First District of Idaho in the 1990s. While in Congress, he served on the influential House Financial Services Committee and the House Natural Resources Committee.

During his tenure on Capitol Hill, he earned respect on both sides of the aisle for his tenacious approach to legislating. He steered multiple legislative measures he sponsored into law, and actively worked to influence significant banking and finance legislation on the Financial Services Committee. He was also active in the leadership of the House through his service on the Speaker’s Policy Working Group and as a deputy whip.

After Congress, he served for five years as managing director of the American Bankers Association for affiliate organizations in securities and insurance. In 2000, he co-founded LaRocco & Associates, Inc., with his son, where his client base was domestic and international. In 2003, he joined Fleishman-Hillard Government Relations and led the organization as its president. In 2006, he returned to Idaho to run for lieutenant governor and then for the U.S. Senate in 2008. 

From 2000 to 2002, LaRocco served as president of the U.S. Association of Former Members of Congress (USAFMC), a nonprofit organization composed of 600 former U.S. senators and members of the U.S. House of Representatives. His work focused on international diplomacy, fostering exchanges with parliamentarians abroad and college campus programs; as well as putting the USAFMC on a high-tech and sound financial trajectory. He has served as the co-chairman of a program to bring young professionals from North Africa to Washington, D.C., to become more familiar with U.S. policymaking. LaRocco also served as the co-chair of the Congress to Campus program, where bipartisan teams of two former members of Congress visit U.S. college campuses.

Recently, at the request of the State Department, LaRocco traveled to Egypt, Oman, Kuwait, Czech Republic, Slovak Republic, Sweden, Finland and Iceland to discuss U.S. politics and diplomacy. He has participated in webinars hosted by the State Department and the U.S. Association of Former Members of Congress for discussions with students in the U.S. and abroad. He has taught political science at Boise State University, where his congressional papers are archived, and serves as a director of the Frank Church Institute. 

LaRocco served as a military intelligence officer in the U.S. Army from 1969-1972, attaining the rank of captain.    

He received his undergraduate degree from the University of Portland and attended Stanford University Institute of TV and Radio. He has a Master of Science from Boston University and also studied at the Johns Hopkins School of Advanced International Studies (SAIS) in Washington, D.C.
