This is the text of the bill introduced in the U.S. Senate on March 14, 2019 by Senators John Cornyn (R-TX), Tammy Baldwin (D-WI), Mike Crapo (R-ID) and Sherrod Brown (D-OH) banning the use of federal funds for the purchase of mass transit rolling stock from manufacturers owned by Chinese-based companies (and withholding federal transit funds from agencies that use their own money to purchase such rolling stock). The legislation has a grandfather clause for rail rolling stock purchase contracts entered into before the enactment of the legislation.
