From 1996 to 2009, Lankford was the student ministries and evangelism specialist for the Baptist General Convention of Oklahoma, and he was director of the Falls Creek youth programming at the Falls Creek Baptist Conference Center in Davis, Oklahoma. He stepped down on September 1, 2009, to run for Congress.
In January 2014, Lankford announced he would run in the 2014 Senate special election to succeed Tom Coburn. He subsequently won the June 2014 primary with 57% of the vote, becoming the Republican nominee for the November election. He won with nearly 68% of the vote.
Lankford was born March 4, 1968, in Dallas, Texas, the son of Linda Joyce (née House) and James Wesley Lankford. His mother was an elementary school librarian. His maternal grandparents owned a small dry-cleaning business, his father and paternal grandparents a dairy farm. His stepfather was a career employee of AC Delco, the parts division of General Motors.
His parents divorced when he was four; his mother and older brother and he lived for a time in his grandparents' garage apartment. He became a Christian at eight. His mother remarried when he was twelve, and the family moved to Garland with his stepfather. Lankford attended Lakeview Centennial High School in Garland. While at Lakeview Lankford participated in the Close Up Washington civic education program. He earned a Bachelor of Science degree in Secondary Education (specializing in Speech and History) at University of Texas at Austin in 1990, and a master's degree in Divinity at Southwestern Baptist Theological Seminary in 1994.
After graduating, he moved to Edmond, a suburb of Oklahoma City, where he still lives today. He served with the Baptist General Convention of Oklahoma. He became the program director of Falls Creek, the largest Christian camp in the U.S.
After two-term incumbent Republican Mary Fallin announced she was giving up her seat to make what would be a successful run for Governor of Oklahoma, Lankford entered the race to succeed her. He finished first in a seven-way Republican primary—the real contest in this heavily Republican district—and defeated former State Representative Kevin Calvey in the run off. He then routed Democrat Billy Coyle in the general election, winning with 62.53% of the popular vote.
Lankford defeated Democrat Tom Guild with 59 percent of the vote. Following the election, he was named chairman of the House Republican Policy Committee, the fifth-ranking position in the House Republican caucus. This is a very senior position for a second-term House member.
Lankford supports simple budget austerity through lowering taxes and reducing government spending. He took the taxpayer protection pledge promising to support no new taxes. He supports the repeal of the income and estate taxes and supports a sales tax to tax consumption and not savings or earnings.
Lankford is a supporter of budget austerity and thus supports prioritizing spending if the debt limit is reached and the Cut-Cap-and-Balance Pledge. He also supports a balanced budget amendment and voted to terminate the Home Affordable mortgage Program.
He supports compensatory time-off for overtime workers and received a 100% rating by the CEI, indicating a pro-workplace choice stance.
Lankford supports loosening restrictions on interstate gun purchases. He opposes firearm microstamping, a controversial method of imprinting casings with a unique marking to match it with a specific firearm, and would allow veterans to register unlicensed firearms.
Lankford supports extending the Patriot Act and expanding roving wiretaps occurring in the US. Lankford supports the prioritization of security, starting with military bases.
He supports expanding exploration of gas and oil both domestically and on the outer continental shelf. He opposes the EPA regulating emission standards as he believes it hinders economic growth.
In addition to barring the EPA from regulating emission standards, Lankford believes manure and other fertilizers should not be classified as pollutants or hazardous.
Lankford has stated his belief that federally funded healthcare is unconstitutional and has made a statement that he will oppose any and all moves for a federal healthcare system. He supported an initiative to allow Medicare choice and also institute budget cuts.
Lankford opposes abortion. He supports banning all federally funded abortions and believes Congress should recognize life at the moment of fertilization. He opposes any federally funded healthcare or coverage programs that allow for abortion, as well as Planned Parenthood and other similar groups. He also opposes forced abortions by the UN Population Fund.
Lankford believes marriage is a union between a man and woman. He has also stated that being gay is a choice and should not be protected from workplace discrimination. He said he believes the distinction lies in a person's choice to act on their sexual orientation.
