Ranking Member


In 2006, Claire became the first woman elected to the U.S. Senate from Missouri, winning the seat once held by Harry Truman.

Making good on a campaign pledge, Claire waged a successful six-year effort to rein in wasteful wartime contracting practices in Iraq and Afghanistan - modeled on Harry Truman's famous battle against war profiteering. During the final hours of Claire's first Senate term, her signature legislation implementing historic wartime contracting reforms was signed into law.


Claire's efforts led to the creation of a new Senate panel charged with financial and contracting oversight. As Chairman, Claire led nearly 40 hearings, and launched an even greater number of investigations at 22 dozens of federal departments and agencies, resulting in more than 30 instances of misconduct referred to federal investigators.

Claire drew on her personal commitment to America's military veterans, helping to pass the 21st Century GI Bill, and establishing a veterans' "secret shopper" program to improve health care services for Missouri's veterans. Following reports of neglect, Claire successfully pushed for the removal of Army officials managing Walter Reed Army Medical Center - and shortly after, led the successful effort to reform management of Arlington National Cemetery after disclosures of mismarked gravesites. Later, she passed into law a comprehensive plan fixing the Pentagon’s troubled program to recover American personnel who are prisoners of war and missing in action (POW/MIA).

Claire teamed up with her Republican colleagues to establish a ban on Congressional earmarks, and has helped lead efforts to repeal automatic pay raises for Congress. She bucked her party's leadership, authoring a bill to impose a cap on federal discretionary spending - legislation which came within one vote of Senate passage.

And when dozens of small towns across rural Missouri were threatened with post office closures, Claire waged a successful battle to protect those post offices - which Claire called "the lifeblood of rural Missouri."

Following Claire's resounding reelection in 2012, her oversight panel was expanded and tasked with protecting taxpayer dollars and investigating waste, fraud, and abuse at every federal agency. A recognized tech leader - with a penchant for communicating directly with constituents via Twitter - Claire also served as Chairman of the Commerce Subcommittee on Consumer Protection. In her second term, Claire launched investigations into areas including fraudulent robocalls, financial management at the U.S. Energy Department, inaccuracies on credit reports, security clearance background checks, pervasive fraud and waste in an Army National Guard recruiting program, and sexual violence on college and university campuses.

And as a senior member of the Armed Services Committee, Claire drew upon her years as a courtroom prosecutor in leading the successful effort to reform how the military justice system handles sexual assaults in our Armed Forces - successfully enacting sweeping changes to protect and empower survivors and hold perpetrators and commanders accountable.

As Missouri's Senator, Claire has earned a reputation as a plain-spoken, independent voice for Missouri's families and businesses  - willing to buck her own party to do what's right, and fighting to expand opportunities for Missouri's kids and grandkids.

Claire returns home to Missouri nearly every weekend, where she loves spending time with her eight grandchildren. She and her husband Joseph have a blended family of seven children, all but two of whom live in St. Louis.
