Interview with Sen. Mark Warner on "Face the Nation," March 30, 2025

CBS News

MAJOR GARRETT: We're pleased to have Senator Mark Warner, the Virginia Democrat and Vice Chair of the Senate Intelligence Committee, with us today. Welcome, Senator Warner. We're diving into two significant topics: the recent military actions targeting the Houthis and private communication channels. Let’s begin with the military interventions. Are you in favor of this administration’s more forceful approach in dealing with the Houthis, and could this strategy help in resuming commercial traffic through the Red Sea?

SEN. MARK WARNER: I support decisive measures against the Houthis. The administration is on the right track, though I would prefer if more of our allies were involved. It's concerning that Trump’s America First agenda is seeming to lead us more into isolation. Nonetheless, I concur with taking a firmer stance against the Houthis.

MAJOR GARRETT: There’s an argument that the Biden administration didn’t exert enough pressure. What are your thoughts on this?

SEN. WARNER: The Biden administration definitely took measures, but they might have missed some opportunities to be even more forceful.

Discussion on Secure Communications

MAJOR GARRETT: Let’s pivot to communications. Do you engage with apps like Signal?

SEN. WARNER: Indeed, I use Signal because it offers more security than conventional phones, especially since Chinese groups like Salt Typhoon have breached standard networks. Still, Signal isn't entirely risk-free. It's crucial not to use it for classified data since adversaries like China and Russia aim to infiltrate it. Basic cybersecurity practices are vital to remain protected.

MAJOR GARRETT: Reports indicate a chat mentioning critical Houthi targets and Israeli concerns over potential intelligence leaks. Do you agree with these concerns, and what could be the consequences?

SEN. WARNER: Based on public information, not classified details, I understand why the Israelis would be upset. Carelessly handling sensitive intelligence strengthens their position. The danger is evident from previous incidents where crucial data was exposed. If such negligence continues unaddressed, trust from allies like our Five Eyes partners could erode.

Handling of Classified Information

MAJOR GARRETT: Some Republicans admit past mistakes regarding classified information. Is that sufficient for you?

SEN. WARNER: It's not enough. There's a consistent failure in safeguarding classified data. The public deserves accountability, similar to what happens in the military and intelligence sectors. Yet we see no proactive measures from the administration, like verifying the security of involved devices. I’ve requested the FBI to conduct an inquiry, but there’s been no response.

Concerns Over TikTok Acquisition Talks

MAJOR GARRETT: Shifting to TikTok, Oracle is reportedly discussing potential acquisition frameworks ahead of an upcoming deadline. What insights can you offer?

SEN. WARNER: I'm aware that several parties are interested in TikTok, but if after the sale, the algorithm remains under China's control, it's meaningless. The manipulation potential of this algorithm poses a propaganda risk that shouldn’t be underestimated.

MAJOR GARRETT: Are there legal ramifications?

SEN. WARNER: Keeping control of the algorithm in China would indeed break laws. Interestingly, Trump initially identified TikTok's problems, though I was skeptical until my findings highlighted the severe data and propaganda risks involved.

National Threat Assessment

MAJOR GARRETT: The National Threat Assessment recently highlighted China's strategic moves in Greenland due to its natural resources. How should the current administration respond?

SEN. WARNER: Greenland's resources are valuable, and fostering closer relations is wise. However, the idea of military intervention against Denmark, a NATO ally, is reckless. The administration’s inconsistent foreign policy jeopardizes alliances and weakens America's global standing.

MAJOR GARRETT: The same assessment notes the rising threat of drug cartels over traditional nation-state opponents. What’s your perspective?

SEN. WARNER: While the drug crisis is severe and demands action, the tech rivalry with China will define the coming decades. Russia remains a threat, especially when current policies dismantle protections against election interference.

MAJOR GARRETT: And the lack of mention on climate change in the threat assessment?

SEN. WARNER: Ignoring climate science doesn’t alter its reality. The Arctic, now seeing the emergence of new shipping routes due to ice melt, exemplifies the urgency of addressing these environmental changes.

MAJOR GARRETT: Thank you, Senator Warner, for the insightful discussion.

SEN. WARNER: Thank you, Major.
