After the much-hyped Nunes memo failed to deliver the narrative reset that the White House hoped for, Donald Trump is discussing a shake-up to his West Wing, three sources familiar with the president’s thinking told me. These people say the president is increasingly frustrated that members of his administration aren’t going to war for him, and he’s being encouraged by his daughter Ivanka to bring in new blood. “The president’s view is that allies on the outside are doing a better job defending him than his political shop,” one Republican close to the White House told me. Another outside adviser who regularly speaks with Trump said that the president is regretting some of his Cabinet choices. “He’s saying he should have put Rudy [Giuliani] at State and Chris Christie at Justice.”

Trump has recently told advisers he wants a “killer” to steer the White House’s response to Robert Mueller’s investigation and craft a midterm election message for him to stump on this fall. For Trump, there’s a growing urgency to fill the role. His efforts to stymie Mueller’s probe have so far failed, and the specter of impeachment looms if Democrats win back the House in November. Ivanka, who’s been frustrated with Chief of Staff John Kelly, has told her father that he needs people around him that will put his interests above their own. “She wants to clean house,” a Trump friend told me. “Her view is J.F.K. had Bobby there to have his back.”

The president’s top choice for the strategist position is Jason Miller, who served as communications director for Trump’s presidential campaign. “He wants a killer, and Jason is a killer,” an outside adviser to the White House told me. Trump had wanted Miller to join the administration during the transition, but Miller withdrew after it was revealed he had an extramarital affair during the campaign with former Trump aide A.J. Delgado.
