The intelligence inspector general suggested to the House intelligence committee today that the whistleblower had concerns about multiple actions, CNN is told by sources familiar with the briefing.

The inspector general did not say specifically all the acts of concern involved the president, the sources said. One source said the inspector general referenced “a sequence of events” and “alleged actions” that took place.

Another source disputed that the inspector general provided substantive details regarding the whistleblower claim.

CNN had earlier reported, citing a source familiar with the case, that the complaint was prompted by concerns over a phone call between the president and a foreign leader.

Inspector General Michael Atkinson was pressed for details but was mostly resistant to the queries, saying he is not allowed to provide details of the substance of the complaint because he was not authorized to do so, the sources said. He is discussing the process for his handling of the whistleblower's concerns.

The New York Times was first to report there was more than one action at the heart of the whistleblower complaint.

Clarification: This post has been updated to clarify that the "multiple concerns" may not all pertain to the President.
