U.S. senators have raised security concerns about a new Metro railcar project. The NIST cybersecurity framework will be part of the process now, the transit authority says.

The lawmakers exhorted the subway system's leadership to “take the necessary steps to mitigate growing cyber risks" to new railcars that could be produced by a Chinese company.

The bills' backers aren't too happy about July reports that a Russian oligarch purchased an election vendor operating in Maryland.

The Homeland Security funding bill advancing in the House follows the Trump administration's budget request in imposing severe cuts on the department's Science and Technology Directorate.
