Walker was born and raised in Louisville, Kentucky.[2] He was named after Justin Hayward, the front man for the musical group The Moody Blues.[3] His father is Terry Martin Walker, a real estate appraiser. His mother, Deborah, and father divorced in 1985 after nine years of marriage. Walker says that he was raised by a "a single working mom" who "made indescribable sacrifices to provide me, the first in my family to graduate from college, with the opportunities she didn’t have herself." Terry Walker claims to have also raised Justin, but Justin cut ties from his father once he moved to college. The relationship is still estranged despite attempts from Terry Walker.[3] His step-grandfather, Norton Cohen, was president of the Acme Paper Stock Company and a prominent member of Louisville's Jewish community, while his maternal grandfather, Frank R. Metts, was a millionaire real estate broker who the New York Times characterized as a "power broker in Kentucky."[3]
Walker grew up in a Democratic household, though his mother had supported RepublicanMitch McConnell when Walker was 8 years old.[3][4] Walker became active in Republican politics at an early age. While a student at Louisville's St. Xavier High School, Walker's step-grandfather arranged to have him interview Mitch McConnell for a class paper, and Walker later interned for McConnell as a college student.[3]
After his clerkships, Walker returned to Gibson Dunn from 2012 to 2013. During the Brett Kavanaugh confirmation hearings for the Supreme Court, Walker gave 119 interviews to the media defending Kavanaugh, and gave several paid speeches to the Federalist Society.[3] He has been a member of the Federalist Society since 2006.[9][1]
From 2015 to 2019, Walker was a professor at the University of Louisville School of Law, where he taught legal writing.[10] In July 2018, Walker had a paper published in The George Washington Law Review reflecting on President Trump's dismissal of FBI Director James Comey and arguing, "calls for an independent F.B.I. are misguided and dangerous... the F.B.I. must not operate as an independent agency. It must be accountable to the President."[3]
On June 24, 2019, his nomination was sent to the Senate. On July 31, 2019, a hearing on his nomination was held before the Senate Judiciary Committee.[15] On October 17, 2019, his nomination was reported out of committee by a 12–10 vote.[16] On October 24, 2019, the United States Senate invoked cloture on his nomination by a 50–39 vote[17] and later that day his nomination was confirmed by a 50–41 vote.[18] He received his judicial commission on October 25, 2019. His service terminated on September 2, 2020, due to elevation to the court of appeals.[19]
In April 2020, Walker blocked LouisvilleMayorGreg Fischer from implementing an order preventing drive-in church services on Easter to prevent the spread of the coronavirus. Walker compared the order to "the pages of a dystopian novel", and said that Fischer "criminalized the communal celebration of Easter".[4]Vox described Walker's opinion as "oddly partisan", noting that there was no actual ban on drive-in church services,[20] and that Fischer had twice attempted to contact the court to communicate this fact, which would have rendered the case moot.[21]The Volokh Conspiracy described the opinion's rhetoric as "over-the-top"; the decision irrelevantly listed deceased former Klan members affiliated with the Democratic Party.[22][20] In August 2020, Walker ruled that photographer Chelsey Nelson is not bound by the Louisville Fairness Ordinance and cannot be compelled to photograph same-sex weddings, which she opposes due to her Christian faith.[23]
D.C. Circuit
On April 3, 2020, President Donald Trump announced his intent to nominate Walker to serve as Circuit Judge on the United States Court of Appeals for the District of Columbia Circuit.[24] On May 4, 2020, his nomination was sent to the Senate. President Trump nominated Walker to the seat being vacated by Judge Thomas B. Griffith, who retired on September 1, 2020.[25] According to The New York Times, Walker's nomination was handpicked by Senate Majority Leader Mitch McConnell.[3] Walker has been described as McConnell's protégé.[4] In early March 2020, McConnell flew to Kentucky to participate in an investiture ceremony for Walker.[4] At the time of his nomination, Walker had no trial experience and had less than six months of experience as a judge.[3] On May 5, 2020, the American Bar Association rated Walker as "Well-Qualified" to serve on the Circuit Court. The ABA sent a letter to the Senate Judiciary Committee explaining their rating after deeming Walker "Not Qualified" when he was nominated for his district court judgeship. The letter said "the Standing Committee believes that Judge Walker possesses a keen intellect, and his writing ability is exemplary. Judge Walker also has significant appellate experience, having clerked for both the D.C. Circuit and the Supreme Court of the United States. Additionally, since our last rating, Judge Walker has served as a federal trial judge."[26][4][27] On May 6, 2020, a hearing on his nomination was held before the Senate Judiciary Committee.[28] On June 4, 2020, his nomination was reported out of committee by a 12–10 vote.[29] On June 17, 2020, the Senate invoked cloture on his nomination by a 52–46 vote.[30] On June 18, 2020, his nomination was confirmed by a 51–42 vote.[31] He received his judicial commission on September 2, 2020.[19]
