A Senate panel has approved a significant defense bill that includes provisions to bar defense contractors from engaging in stock buybacks and paying dividends. This move comes amid ongoing scrutiny of corporate financial practices, notably those involving taxpayer money. Additionally, efforts to codify previous executive orders aimed at limiting defense stock buybacks have gained traction, despite opposition from some Republicans who blocked measures intended to restrict investments that could benefit the Trump family. The legislation also seeks to give the Pentagon a more active role in equity investments, raising questions about the management of contractor portfolios and their obligations to taxpayers.
