President-elect Donald Trump wants officials in his administration to commit not to lobby for five years after leaving their posts. But that doesn’t mean they won’t be able to find lobbying work after they depart.

Trump’s lobbying ban would apply only to the executive branch. So former Trump administration officials would still be free to lobby Congress, said Lisa Gilbert of Public Citizen, a government watchdog group based in Washington.

What’s more, even with the ban limited to the executive branch, there could be ways around it. “The definition of lobbyist is very narrow,” Gilbert said. Former administration officials could call themselves consultants or use another title and put their experience to work for corporations or other interests.

As the nonprofit Sunlight Foundation notes, lobbyists are required to register if they spend at least 20% of their time lobbying on behalf of a client. But, says the foundation, the threshold is “reasonably easy to get around.” In a blog post on “shadow lobbying,” the foundation cites the example of former Sen. Tom Daschle, who worked as a “policy adviser” at lobbying firms after leaving the Senate in 2005. (Daschle did register as a lobbyist in March of this year.)

Trump campaigned on the lobbying ban, and his transition team reiterated it this week. It includes a lifetime ban on ex-administration officials representing foreign governments, Republican National Committee spokesman Sean Spicer said on a conference call with reporters Thursday.

Trump’s team dug in on the ban following Vice President-elect Mike Pence’s order this week to remove all lobbyists from the transition. The president-elect was criticized for including lobbyists on the transition team after running on a vow to “drain the swamp” in Washington.

“Everybody’s a lobbyist down there,” Trump said on an episode of “60 Minutes” broadcast on Sunday night.

In response to a question about lobbyists being on the transition, he said: “I’m saying that they know the system right now, but we’re going to phase that out.”
