Watchdog files ethics complaint against House Intel staff over alleged text message leak

The messages appeared in a Fox News article in February.

The incident raises questions about whether the partisan infighting that has slowed the House probe is suddenly impacting Senate investigators as well.

A committee spokesperson did not respond to a request for comment.

The messages, which appeared in a Fox News article in February, detailed efforts to arrange a meeting with Christopher Steele, the former British spy who compiled the infamous dossier of unverified allegations of collusion between the Trump campaign and Russian agents.

"The speaker heard the senators on their concerns and encouraged them to take them up directly with their counterparts," a spokesperson for Speaker Ryan told ABC News.

Neither Warner nor Burr would discuss the particulars of the meeting with ABC News.

“We talked to the Speaker about the extent of our [Russian meddling] investigation, and that was the extent of it,” Burr told ABC News. “We made no requests of the Speaker. Zero. Nada.”

Warner, however, questioned some of his colleagues’ commitment to the investigation.

“We are not going to let any individual or any group interfere with this bipartisan effort to get to the truth,” Warner said. “I know we’re looking for the truth. I’m not sure that the same can be said about all the other efforts.”

Asked explicitly about whether Nunes was responsible for the leaks, Schiff said, “You would have to ask him, but it clearly came from the majority.”
