A former Verizon employee probably has no more ties or vested interests in Verizon anymore. If they have stock or other interests then they shouldn’t be in those regulatory offices.
The quid pro quo usually comes later, after they leave their government post. In the form of board seats or high level positions in the companies that benefited. So, hard to police since the payoff is down the road.
ethics have gone out the window for this presidency, shouldn't doesn't matter anymore
