William Todd Tiahrt[2] (/ˈtiːhɑːrt/ TEE-hart; born June 15, 1951) is an American politician who served as the U.S. representative for Kansas's 4th congressional district from 1995 to 2011.

Then, in 2017, after Pompeo vacated the seat to become President Donald Trump's CIA Director, Tiahrt sought the Republican nomination for the special election to fill it, but came in third, losing to Kansas state treasurer Ron Estes.

After only one term, in 1994, he won the Republican nomination for the 4th Congressional District and was elected in an upset over 18-year Democratic incumbent Dan Glickman.

In November 1997, Tiahrt was one of eighteen Republicans in the House to co-sponsor a resolution by Bob Barr that sought to launch an impeachment inquiry against President Bill Clinton.

[20] Additionally, the law blocks any data legally released from being admissible in civil lawsuits against gun sellers or manufacturers.

The A+ ranking took into consideration the letter he submitted to court briefs that he signed as a "critical friend of the court briefs"[23] in the 2008 landmark case District of Columbia v. Heller, in which the Supreme Court of the United States ruled that the Second Amendment protects an individual's right to possess a firearm unconnected with service in a militia for traditionally lawful purposes, such as self-defense within the home, and that Washington, D.C.'s handgun ban and requirement that lawfully-owned rifles and shotguns be kept "unloaded and disassembled or bound by a trigger lock" violated this guarantee.

[26] A bill was introduced by Tiahrt and Congressman Brian Bilbray (R-CA) called the Fairness for American Students Act that would close a loophole in current law that several states have used to provide lower-cost college tuition to illegal immigrants compared to tuition rates U.S. citizens from neighboring states have to pay.

[39] The "Tiahrt Amendment" of 1998, which was most recently included in the FY2020 State-Foreign Operations Appropriations Act, ensures that no government funding is used in connection with forcible sterilizations in foreign countries.

Further, the amendment requires that any experimental contraceptive drugs and devices and medical procedures are provided only in the context of a scientific study in which participants are advised of potential risks and benefits.

[41] Concern that the U.S. Agency for International Development (USAID) was possibly funding a forced sterilization campaign in Peru led Tiahrt to enact the Amendment.

[40] Tiahrt was cited as responsible for preventing the City of Washington D.C., from spending federal or District funding on "needle exchange programs" for drug users from 1998 through 2007.

On July 24, 2004, the Tiahrts' youngest child, sixteen year-old Luke, died of an apparent suicide at the family home in Virginia.
