CLEVELAND (Reuters) - If he wins the presidency, Republican presidential nominee Donald Trump would seek to purge the federal government of officials appointed by Democratic President Barack Obama and could ask Congress to pass legislation making it easier to fire public workers, Trump ally, Chris Christie, said on Tuesday.

Christie, who is governor of New Jersey and leads Trump’s White House transition team, said the campaign was drawing up a list of federal government employees to fire if Trump defeats Democratic rival Hillary Clinton in the Nov. 8 presidential election.

“As you know from his other career, Donald likes to fire people,” Christie told a closed-door meeting with dozens of donors at the Republican National Convention in Cleveland, according to an audio recording obtained by Reuters and two participants in the meeting.

Christie was referring to Trump’s starring role in the long-running television show “The Apprentice,” where his catch-phrase was “You’re fired!”

The Trump campaign did not respond to requests for comment.

Trump’s transition advisers fear that Obama may convert these appointees to civil servants, who have more job security than officials who have been politically appointed. This would allow officials to keep their jobs in a new, possibly Republican, administration, Christie said.

“It’s called burrowing,” Christie said. “You take them from the political appointee side into the civil service side, in order to try to set up ... roadblocks for your successor, kind of like when all the Clinton people took all the Ws off the keyboard when George Bush was coming into the White House.”

Christie was referring to pranks committed during the presidential transition from Bill Clinton to George W. Bush in 2001. During that period, some White House staffers removed the W key on computer keyboards and left derogatory signs and stickers in offices, according to a report by the General Accounting Office, an investigative arm of Congress.

“One of the things I have suggested to Donald is that we have to immediately ask the Republican Congress to change the civil service laws. Because if they do, it will make it a lot easier to fire those people,” Christie said.

He said firing civil servants was “cumbersome” and “time-consuming.”

Christie also said that changing the leadership of the Environmental Protection Agency, long a target of Republicans concerned about over regulation, would be a top priority for Trump should he win in November.

Trump has previously vowed to eliminate the EPA and roll back some of America’s most ambitious environmental policies, actions that he says would revive the U.S. oil and coal industries and bolster national security.

Christie added that the Trump team wants to let businesspeople serve in government part time without having to give up their jobs in the private sector. Trump frequently says he is better equipped to be president because of his business experience.

Although Christie was repeatedly asked during the meeting, he declined to name any potential Cabinet picks. He said Trump was not ready to do that yet.

Responding to Christie’s comments on targeting political appointees on Wednesday, White House spokesman Josh Earnest said that allowing appointees to apply for career civil service positions was “a longstanding precedent.”

“If you want to stack up the ethical record of President Obama and his political appointees against the ethical record compiled by Governor Christie and his political appointees, that we’d welcome that kind of comparison,” he said.

The American Federation of Government Employees, the largest federal employee union in the United States, said while it was concerned about the practice of “burrowing,” current law protected most federal employees from at will firing.

“The federal government is a serious undertaking. It’s not a reality TV show, with ‘You’re fired!’” said Jacqueline Simon, policy director at AFGE.

“Just as we don’t want to hire anybody for political reasons, we don’t want anybody to be fired for political reasons,” she said.

As of March 2016, there were a total of 3,164 political appointees, 852 of whom were presidential appointees.

In its most recent report on the topic, the Government Accountability Office said in 2010 that 143 former political appointees and congressional employees converted to career positions between May 1, 2005, and May 30, 2009.

The Republican-controlled House of Representatives Oversight and Government Reform Committee is investigating the practice of burrowing.

It sent letters dated Wednesday to 23 federal departments and agencies, asking them to document all cases of burrowing that have occurred since Sept. 1, 2015.
