Nunes described the surveillance as most likely being “incidental collection.” This can occur when a person inside the United States communicates with a foreign target of U.S. surveillance. In such cases, the identities of U.S. citizens are supposed to be kept secret — but can be “unmasked” by intelligence officials under certain circumstances.

There you have it folks!!! the information was gathered because Trumps team was communicating with foreign agents! I think Senator Nunes just helped impeach President Trump.
