WASHINGTON (Reuters) -Two U.S. lawmakers on Friday asked the Commerce Department to investigate whether devices sold by Chinese smartphone maker OnePlus in the United States pose security concerns, according to a letter seen by Reuters.

Representative John Moolenaar, a Republican who chairs a House of Representatives committee on China, and the panel's top Democrat, Representative Raja Krishnamoorthi, noted that major U.S. retailers sell OnePlus devices for use on two U.S. wireless networks.

The lawmakers said a recent analysis by a commercial company provided to the committee "indicates that these devices may potentially collect and transmit extensive user data -- including sensitive personal information to "servers under Chinese jurisdiction without explicit user consent."

Shenzen-based OnePlus did not immediately respond to requests for comment.
