Paragraph 1(b) of Senate Rule XIX, however—commonly known as the Pastore rule, after its author, former Rhode Island Senator John Pastore—requires Senate floor debate to be germane during specific periods of a Senate work day. Pursuant to the Pastore rule, all floor debate must be germane and confined to the specific question then pending before the Senate for the first three hours after (1) the conclusion of the Morning Hour occurring at the beginning of a new legislative day (in the rare event the Senate should hold a Morning Hour) or (2) after the unfinished business or any pending business has been laid before the Senate on any calendar day. The Pastore rule's germaneness requirement can be waived by unanimous consent (UC) or by nondebatable motion. Enforcing Germaneness in Debate

A Senator may be called to order during the three-hour window described in the Pastore rule if his or her remarks are not germane to the specific question then pending before the Senate. In current practice, the germaneness requirements of the Pastore rule are rarely formally invoked on the Senate floor. If a Senator calls another Senator to order under the rule, enforcement first results in a reminder from the presiding officer that debate must be germane to the question then pending before the Senate. The raising of this point of order does not remove speaking privileges from the offending Senator, although the Senator must suspend his or her remarks until the chair rules on the question. Depending on the ruling of the presiding officer on such a point of order, a Senator may either continue speaking (if his or her debate is ruled germane), pivot to a germane topic (if ruled not germane), or yield the floor (if ruled not germane).
