The Freedom of Speech in Debate

"The freedom of speech in debate in the House of Representatives should never be denied or abridged, but freedom of speech in debate does not mean license to indulge in personal abuses or ridicule. The right of Members of the two Houses of Congress to criticize the official acts of the President and other executive officers is beyond question, but this right is subject to proper rules requiring decorum in debate."       - Cannon's Precedents, Volume 8, Section 2497
