One day after the attack, Mr. Hannity sent a text message to Kayleigh McEnany, then the White House press secretary, describing a five-point plan for approaching conversations with the president, according to documents released by the House committee investigating the Jan. 6 riot.

After urging Ms. McEnany to avoid discussion of a “stolen election,” Mr. Hannity proffered another talking point to use with Mr. Trump: “Yes, impeachment and 25th amendment are real, and many people will quit …”

Mr. Hannity appeared to be referring to the possibilities that Mr. Trump could be impeached, face mass resignations from his staff or be temporarily removed from office by a group of his cabinet secretaries invoking the 25th Amendment.

Ms. McEnany replied: “Love that. Thank you. That is the playbook. I will help reinforce.”
