President Trump wrote in a tweet Saturday morning that Republicans have an "obligation" to fill Justice Ruth Bader Ginsburg's seat on the Supreme Court following her death Friday.

What he's saying: "We were put in this position of power and importance to make decisions for the people who so proudly elected us, the most important of which has long been considered to be the selection of United States Supreme Court Justices," the president said. "We have this obligation, without delay!"
