Bolton tops Trump 'enemies list' as president mulls 'payback' after impeachment acquittal

President Trump wants to get back at those on his enemies list, and former national security adviser John Bolton is reportedly at the top.

"He has an enemies list that is growing by the day," a source told Vanity Fair on Monday. A "prominent Republican" added that "it's payback time" for Trump.

"Trump’s playbook is simple: Go after people who crossed him during impeachment," the person said, adding that additional possible targets could include Rep. Adam Schiff, Rep. Jerry Nadler, and Sen. Mitt Romney.

Several sources added that Bolton was the president's No. 1 target. Trump's plan of attack could include a criminal investigation into his former adviser.

"Trump has been calling people and telling them to go after Bolton," a source close to private conversations said, adding that the president wishes for Bolton to be criminally investigated.

Another source said that Trump believes Bolton improperly handled classified information and that the White House might leak emails from him showing abuse by the former adviser. A former official said the emails could include exchanges "showing [Bolton] was doing pay-to-play." Bolton's camp has dismissed the claims, saying, "John plays things straight."

The fight comes as sections of Bolton's book have been leaked to the press, which undermined Trump's impeachment defense. The White House has claimed Bolton's book contains top-secret information and sent a cease-and-desist letter demanding that it not be published.
