Lawmaker probes tech firms that ran Clinton's server

Rep. Lamar Smith, chairman of the House Committee on Science, Space and Technology, fired off a series of letters Thursday to firms that provided tech support to Hillary Clinton's private server in an effort to learn more about the cybersecurity measures Clinton used to protect her emails.

"A high profile government official deviating from established information security requirements raises significant concerns," Smith said of the four letters he sent out Thursday. "The sensitive nature of the information stored on Sec. Clinton's private server created a unique challenge to ensure all of the information was properly safeguarded."

Two of Smith's letters went to Datto, Inc. and Platte River Networks, tech companies known to have provided services to Clinton during her State Department tenure.

The other pair of letters went to Fortinet, Inc. and SENCAP Network Security Corp., two firms whose role in managing the Clinton email server was not well known.
