Stricture Against Personalities in Debate.
The term “personalities” is generally understood in this context to mean critical personal references. Representatives are prohibited from referring negatively to individual Members, identifiable groups of Members, the Speaker, the President, or the Vice President. This prohibition also has been applied to nominated candidates for President and Vice President, including those who are not Members of Congress or an incumbent President or Vice President. Similar restrictions apply to remarks about individual Senators.
House precedents provide guidance on what constitutes engaging in personalities in debate when different categories of individuals (e.g., the President, another Representative, the Speaker) are the subject of remarks made on the House floor. Some important principles that emerge from these precedents are presented below...[snip]
References to the President of the United States.
Criticisms of the President’s official policy actions and opinions are permitted. Members may question the President’s political motivation, but any questioning of the President’s personal motivation is out of order.
Members may not engage in personal abuse, innuendo, or ridicule of the President. It is out of order to question the President’s personal conduct, “whether by actual accusation or by mere insinuation. References to the President that have been ruled unparliamentary include calling the President a “liar,” attributing “hypocrisy” to him, accusing him of “demagoguery,” and alluding to alleged personal misconduct or a “propensity for unethical behavior” on the President’s part.
Members may not quote from a person or a source, such as books and newspapers articles, using a “derogatory term” in reference to the President.
It is not in order to address remarks directly to the President in House floor debate (e.g., “Mr. President, keep your word to the American people”).
The Speaker has held that principles of decorum governing references to the President do not necessarily apply to references to the President’s family
Fwiw, I did not read it all, but I think these rules only apply to conduct on the floor of the House
