Thank you.
I want to point out to the committee that I have a document from the United States Department of Homeland Security dated November 2020. Paragraph 13 confirms that it's very easy to steal data from Nuctech's devices and that this poses a security issue. Our American colleagues confirm that there's a security issue in this area.
I have some time left, so I'll turn to Mr. Bergen.
Mr. Bergen, we discussed the purchase of foreign technology. You said that Nuctech is another example in a series of failures in our procurement system and that billions of dollars were paid to foreign technology firms that failed to deliver on what they promised.
Can you tell us more about this? When you talk about billions of dollars, how many companies and individuals are involved? Can you elaborate on this?
