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 hearing gives a snapshot of the threats at the forefront of U.S. intelligence chiefs’ minds, and foreign hacking featured prominently.

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 proposed bill comes as the government increases pressure on China for allegedly using its corporate presence in the U.S. to steal intellectual property.

The reports, released by the Senate Intelligence Committee, represent the most comprehensive independent analyses of the 2016 Russian disinformation effort.

The Senate Intelligence Committee's top Democrat urged the U.S. to heed the lessons of Russia's intervention in the 2016 election.
