Justice Ruth Bader Ginsburg’s death on Friday, just six weeks before Election Day, has unleashed a battle over whether President Donald Trump should nominate — and the Republican-led Senate should confirm — her successor, or whether the seat should remain vacant until the outcome of the 2020 Presidential Election is determined.

Trump had previously named more than 40 people to choose from to fill a potential vacancy on the Supreme Court. The names of his first two nominees, Justice Neil Gorsuch and Justice Brett Kavanaugh, appeared on the lists before their nominations. The most recent additions to Trump’s list came earlier this month.
