• Trump is reportedly building a list of those who have "crossed him"
  • At the top is Bolton, who Trump may ask to be criminally investigated
  • Sen. Mitt Romney is also on Trump's list

As the Senate wraps up its impeachment trial, President Donald Trump is looking ahead – he’s already planning how he will retaliate against those behind the impeachment and those who betrayed him.

A new report from Vanity Fair details the president’s quiet work to assemble a list of “people who crossed him during impeachment,” as an unnamed insider explained. Trump’s list includes Rep. Adam Schiff, D-Calif., Rep. Jerry Nadler, D-N.Y., and Sen. Mitt Romney, R-Utah.

At the top of his list, though, is former national security adviser John Bolton. It’s not difficult to see why: Bolton has, over the past month, not only said he’d be willing to appear as a witness in the Senate, but early leaks from his upcoming book cast Trump in a very poor light. His book allegedly confirms accusations that the president threatened to withhold military aid to Ukraine if they did not investigate former Vice President Joe Biden’s son, Hunter Biden. It also allegedly details Bolton’s efforts to protest Trump’s dealings with Ukraine.

Last month, the White House said that after vetting Bolton’s book they could not allow it to be published without several important edits.

Trump’s ire towards Bolton is reportedly so great, Trump’s “been calling people and telling them to go after” him, an insider told Vanity Fair. They also said that Trump is also considering ordering a criminal investigation into the former White House adviser. The White House is selecting several emails from Bolton portraying him as “doing pay-to-play,” in order to justify an investigation, according to the insider.

While it’s also not terribly difficult to see why Trump might not hold Schiff and Nadler in the highest regards – not only were they key players in the push for impeachment, but Schiff also served as the House impeachment manager during the trial – he’s butted heads with Romney on several occasions before and after entering the White House.

Despite their difficulties, Romney and Trump have had a relatively civil, though uneasy, relationship in the past. That has drastically changed over the course of the impeachment trial though.

Last week Democrats finally got their wish to have a vote on whether or not to call witnesses for testimony, but they failed to secure enough votes from Republicans. Romney was one of the few to break with his party, voting with Democrats, after being openly critical about Trump’s actions.

He’s already facing backlash from the Republican Party. The Conservative Political Action Conference, or CPAC, has already revoked his invitation to their gathering this year.
