I whanau a Kirk i Austin, Texas, he tohu ia no te John H. Reagan High School o Austin, Austin College, me te Whare Wananga o Texas School of Law. Mai i te 1994 ki te 1995, i mahi a Kirk hei Hekeretari o te Kawanatanga o Texas, tae noa ki tana pooti hei Koromatua o Dallas, i mahi ai ia mai i te 1995 ki te 2002 me te tangata tuatahi o Awherika-Amerika ki te pupuri i tetahi o aua tuunga. I rere ia mo te United States Senate i te 2002, engari i hinga ia e te hoa riri Republican a John Cornyn. I muri i tana hinganga, i mahi a Kirk hei hoa i te umanga ture a Vinson & Elkins i Houston me te mahi hei kaitautoko mo te Energy Future Holdings me Merrill Lynch. I tohua a Kirk e te Perehitini a Barack Obama hei mema mo te US Trade Representative i te Poutu-te-rangi 18, 2009, a, i whakapumautia e te US Senate i te pooti 925.
