However, Massachusetts Senator Elizabeth Warren introduced a bill in 2018 that sought to do what Cruz and Ocasio-Cortez discussed on Twitter Thursday.
Warren's Anti-Corruption and Public Integrity Act would place a lifetime ban on former presidents, vice presidents, federal judges, Cabinet members and members of Congress from becoming lobbyists after the end of their political careers. All other government officials would have multi-year bans set that would prevent an individual from lobbying for at least two years after leaving a government post.
The bill also would have prevented government officials from owning individual stocks and require the president and vice president to place any "conflicted assets" in a blind trust, which would then be sold. Senior government officials and White House staff members would also be required to eliminate any privately-owned assets that could generate a conflict of interest, the bill says.
Warren's bill, as well as a companion House Bill introduced by Reps Pramila Jayapal (D-Wash.) and John Sarbanes (D-Md.), did not advance out of committees during the 115th congressional session.
