Donald Trump's staff has announced a tough new anti-lobbying for all members of his transition team and all other officials who work for the President-elect.

People who work with Trump must sever all their ties to the lobbying industry, and they are not allowed to lobby on behalf of anyone for five years after they leave the Donald's side.

The ban also applies to the transition team members charged with helping to find, vet and hire for the incoming Republican administration, Trump spokesman Sean Spicer said late Wednesday in New York.

Additionally, neither the transition advisers nor incoming officials are permitted to be registered federal or state lobbyists, Spicer said. He described the measures as helping to ensure people won't be able to use government service 'to enrich themselves.'

The Trump team did not explain how the ban would be enforced.

Trump also wants to 'expand the definition of lobbyist so we close all the loopholes that former government officials use by labeling themselves consultants and advisers when we all know they are lobbyists.'

Senate Majority Leader Mitch McConnell did not answer questions about the lobbying ban on Wednesday.

When he was asked by reporters, McConnell instead said he hopes legislators 'address the real concerns of the American people' rather than fixate on every utterance during the presidential contest.

However, the plan has been met with some criticism, with experts saying it will seriously impact Trump's ability to get a capable team in place.

'This will have a chilling effect on his hiring, no doubt,' Paul Miller, who leads the National Institute for Lobbying and Ethics, said.

It is unclear how many of the thousands of people Trump (pictured during a press conference) is due to hire will be subject to the lobbying ban

'Most people who agree to government service want to go back into the private sector. We don't want career politicians, and that's what he could end up with.'
