“A few words on why Gaetz stunt to storm the SCIF to disrupt Laura Cooper's deposition is a VERY serious national security problem. Note, I worked in that SCIF for HPSCI and handled cybersecurity issues while there.”

“Aside from disrupting the testimony of a DoD official shedding light on the President's attempts to extort a sham investigation into the child of his most feared political rival by withholding military aid that Congress gave to resist a Russian invasion...”

“Storming the SCIF without respecting the security protocols that require people to leave their electronic devices *outside* the space, is actually compromising our national security.”

“First, the SCIF itself is a secure facility designed to prevent electronic eavesdropping so members of Congress can receive highly classified information about how the nation collects information on its adversaries, and on *very* sensitive intelligence operations.”

“Foreign adversaries are constantly trying to figure out what goes on inside those rooms to figure out what the US knows about them, to out US high-level sources in their governments, to know what the US government knows and use it against us.”

“The facilities are carefully designed and controlled to ensure that electronic signals, surveillance methods, or other listening devices do not compromise the information discussed in these rooms. I will not, for obvious reasons, go into details.”

“Bringing electronic devices into a SCIF, and this SCIF in particular is *very* problematic, especially when done by members of Congress. Because Members of Congress (and their electronic devices) are high-value targets for compromise by foreign intelligence services.”

“Members of Congress have access to a wide range of sensitive information, including, in the case of these members, conversations with the President of the United States. They travel internationally, receive emails from the public, and meet with foreign dignitaries.”

“As politicians, they're also highly sensitive to revelations of derogatory information, which means that foreign adversaries are very interested in collecting same.”

“They also tend to be lax in their security protocols. This means they may not know they have been compromised. For example, their phones can be turned into listening devices without their knowledge. https://t.co/NSCUgd1EjP”

“This is why outside HPSCI there is a security guard and a series of cabinets for people to leave (and lock) their electronic devices while they are inside the room. Failure to follow this protocol can violate the security of the entire SCIF.”

“After an incident like this happens, countermeasures have to be taken to ensure the SCIF is not compromised. It is a time-consuming, technical process, which again, I will not discuss.”

“But in "storming the SCIF" without observing the security protocols, Rep. Gaetz et al, endangered our national security & demonstrated they care more about a political stunt than protecting intelligence information. I cannot emphasize enough how serious this is.”

“To ensure that the information was secure, the members should give over their electronic devices for scanning to ensure no malware was on them, and that they have not compromised the SCIF. If they don't want to give them up, they should have checked them before entering.”

“So, to recap: To disrupt testimony from a DOD official on how the President endangered national security for both the US and Ukraine by withholding military aid, the President's allies further endangered national security by storming the SCIF with their electronic devices.”
