The White House is reaching out to political allies and conservative activist groups to prepare for an ailing Justice Ruth Bader Ginsburg’s possible death or departure from the Supreme Court — an event that would trigger the second bitter confirmation battle of President Donald Trump’s tenure.

The outreach began after Ginsburg, 85, on Monday missed oral arguments at the court for the first time in her 25 years on the bench. The justice, who was nominated to the court by President Bill Clinton in 1993, announced in late December that she underwent a surgical procedure to remove two cancerous growths from her lungs.
