Former President Donald Trump’s transition operation involves compiling lists of names of people deemed unworthy of serving in a second Trump administration.

The lists of undesirable personnel include people linked to the Project 2025 political plan; officials who resigned in protest of Trump’s response to the January 6, 2021 attack on the U.S. Capitol; and others perceived as disloyal to the former president, said two former Trump officials who were granted anonymity to discuss private transition operations.

The effort is the latest indication that a second Trump administration could have a very different staff makeup than the first, in positions ranging from the highest-ranking aides to lower-level appointees. The former president and his allies have long emphasized the value of staff loyalty, and they appear eager to avoid the leaks and staff turnover that plagued Trump during his first term.

Donald Trump Jr. — Trump’s son and honorary chairman of the transition team — is leading the effort to gather the names of banned staffers, a former Trump official said.
