* Gabby Orr and Caitlin Oprysko report that some of Trump's own people are worried he can't let the Mueller report go:

White House allies are starting to worry that Trump’s inability to move on to other subjects, or at the very least stick to playing up Mueller’s conclusion that his campaign did not engage in a criminal conspiracy with the Russian government, is doing more harm than good. One former Trump campaign official described the president’s post-Mueller volley as “a complete and utter disaster,” suggesting that Trump is likely to generate another negative news cycle for himself when he sits down for an interview with longtime pal and Fox News host Sean Hannity Thursday night.

“Obviously it’s not a smart strategy,” said a former White House official, who noted that there are “very few” West Wing staffers left who are likely to tell the president to move on. “He needs to let it go. It’s especially not helpful to him, but he just can’t help himself."

But let’s have another hundred articles about how the ones really struggling with this are the Democrats.

* Colby Itkowitz reports on another investigation beginning in the House:

Three powerful House committees opened an investigation into the motives behind President Trump’s recent removal of senior leadership at the Homeland Security Department.

In a letter sent Thursday to the agency’s acting secretary Kevin McAleenan, the panels’ chairmen asked for all communications related to the departure of several individuals, including former homeland secretary Kirstjen Nielsen, who resigned on April 7.

They also requested all communications with White House senior adviser Stephen Miller about department leadership changes.

Chairmen Elijah E. Cummings (Md.) of Oversight, Jerrold Nadler (N.Y.) of Judiciary and Bennie G. Thompson (Miss.) of Homeland Security wrote that they are “concerned that the President may have removed DHS officials because they refused his demands to violate federal immigration law and judicial orders.”

The administration, however, has already refused to allow Miller to testify. You never know what he might say.
