House lawmakers discuss how to address intelligence briefings on Israel without speaker

House lawmakers are scrambling to determine whether acting Speaker Patrick McHenry can participate in a so-called Gang of Eight intelligence briefing on the unfolding crisis in Israel, a source familiar with the active discussions told CNN.

The source said the understanding is that it is ultimately up to the White House whether McHenry – who has the needed clearance – can be part of the leadership briefing, but emphasized how untested the situation is. The Gang of Eight includes the top leaders and heads of the intelligence committees in both parties and both chambers.
