President Joe Biden’s new administration is cracking down on “shadow lobbying” and closing revolving door loopholes — but the initiative preserves at least some of the loopholes that many of his cabinet picks used to enrich themselves after their service in the Obama administration. It also allows the ethics rules to be waived by an office run by Biden’s political appointees.

Biden issued an ethics order Wednesday evening that would poke holes in a notorious Washington con — one where former government officials quickly join lobbying firms and devise strategies to influence their former government colleagues without making any official lobbying contacts themselves, a common way to evade post-employment restrictions and avoid having to register to lobby.

Under the new order, executive branch appointees must agree not to lobby their former agencies for two years. Further, the pledge adds, appointees must say that “for a period of one year following the end of my appointment, I will not materially assist others in making communications or appearances that I am prohibited from undertaking myself.”
