President Trump is discussing with his advisers the possibility of sitting out the general election debates in 2020 because of his misgivings about the commission that oversees them, according to two people familiar with the discussions.

Mr. Trump has told advisers that he does not trust the Commission on Presidential Debates, the nonprofit entity that sponsors the debates, the two people said.

Less of a concern for Mr. Trump than who will emerge as the Democratic nominee is which media personality will be chosen as the debate moderator, according to people in contact with him.
