Chief Judge David Smith, appointed by George Bush in 2002 and raised to chief in 2016. Most renown for investigating organized crime in the 1980s, but since his appointment most of his high-profile cases seem to focus on 1st amendment disputes. He's repeatedly reinforced that religious immunity comes before alleged civil rights violations. https://en.wikipedia.org/wiki/D._Brooks_Smith

Judge Peter Phipps, appointed by Donald Trump last year in July. He worked for the firm 'Jones Day' while it served as legal counsel for Trump's 2016 campaign. Extremely young for such a high-profile judge. https://en.wikipedia.org/wiki/Peter_J._Phipps

Judge David Porter, appointed by Donald Trump in 2018 right before the mid-terms. He attended the Scalia Law School and worked as an editor for its newspaper. Since 1996, he's been the President of the Pittsburg Federalist society. https://en.wikipedia.org/wiki/David_J.Porter(judge)

Stephanos Bibas, appointed by Donald Trump in November of 2017, was one of Trump's first judicial appointments. He is a noted scholar of criminal procedure with expertise in criminal charging, plea bargaining, and sentencing. He used to be a deacon for the 'Orthodox Church.' As a circuit judge in the 3rd, he's frequently been the minority opinion because of his support for the 2nd amendment against NJ regulations. https://en.wikipedia.org/wiki/Stephanos_Bibas

Thomas Hardiman, appointed by George W. Bush at the end of his second term. Hardiman was a finalist to succeed Antonin Scalia as an Associate Justice of the Supreme Court of the United States, alongside the eventual nominee, Neil Gorsuch. More conservative Republicans preferred his candidacy for Supreme Court over Brett Kavanaugh, but he is more moderate on immigration policy https://en.wikipedia.org/wiki/Thomas_Hardiman

Luis Felipe Restrepo, appointed by Barack Obama in 2016. The Senate voted 82-6 for Restrepo. President Trump nominated Restrepo to serve as Commissioner of the United States Sentencing Commission, a seven-member independent body that sets federal sentencing guidelines. It seems Restrepo is respected by both sides because he's more of a textualist on constitutional matters than most Obama-appointments. https://en.wikipedia.org/wiki/Luis_Felipe_Restrepo

Cheryl Ann Krause, appointed by Barack Obama in 2014. She's also relatively young at 52 years old. Krause has served as outside counsel for the City of Philadelphia's Board of Ethics and on the Board of Directors of the Committee of Seventy, a non-partisan civic organization focused on fair elections and government integrity, but she seems far more liberal than any other judge on this list - including Luis Restrepo. https://en.wikipedia.org/wiki/Cheryl_Ann_Krause
