Brett Kavanaugh replaces Justice Kennedy as a US Supreme Court judge, and is expected to keep the position for decades. He was one of the lead writers of the report that led to Bill Clinton’s impeachment, and was a White House lawyer and adviser under the George W Bush administration. A devout Catholic, Kavanaugh is expected to establish conservative control of the court as he becomes Trump's second appointment to the nation's highest judicial body. The Supreme Court’s decisions have a profound impact on American society. It is often the final word on highly contentious laws. Disputes involving abortion, immigration, gay rights, voting rights and transgender troops could all be ruled on soon. Kavanaugh is expected to cast conservative votes in all of them. He is against abortion and supports the right to bear arms including semi-automatic weapons. Historically he has ruled against regulations regarding air pollution and climate change.
