Credit four former attorneys general of the United States for insisting that issues related to the Supreme Court should play a prominent role in this fall’s presidential election.

The four former top legal officers of the U.S., all Republicans, sent a letter Tuesday morning to ABC network executives saying the network’s moderators for the scheduled Sept. 10 presidential debate should ask two court-related questions. Their letter said that so far in this campaign, “the presidential candidates have had little opportunity to explain their stances” on Supreme Court topics.
