Warren's new plan comes ahead of a Thursday campaign appearance in Virginia. The Democratic presidential candidate cited Patrick Shanahan, the onetime Boeing executive tapped by President Donald Trump to be the next Pentagon chief, as an example of the "obvious potential conflicts of interest" her proposal is designed to prevent.
Warren wrote Thursday that the existing regulations are "far too weak" to limit the undue influence of giant military contractors at the Pentagon. Her plan would also limit former national security officials' ability to work for foreign governments.
