Kavanaugh sits on the DC Circuit Court. That is the main federal appeals court — often considered a stepping stone to the Supreme Court as it hears some of the most prominent cases, including ones filed against federal legislation like Obamacare. So it’s not a huge surprise President Trump selected a member from it.
Kavanaugh worked as associate counsel to pro-life President George W. Bush and he came out of the era of Reagan judicial appointees. His rulings have been said to be more like Scalia than Kennedy, however.
