President Donald Trump’s former attorney, Michael Cohen, has increasingly taken center stage in House investigations and is living rent-free in the president’s head.

Having pleaded guilty to a fraudulent scheme to pay off women who say they had affairs with the president to influence the 2016 presidential election, Cohen is one of the few people that emerged from inside Trump’s inner circle willing to talk about his former boss’ alleged violations of the law. In his congressional testimony last week, he brought hard evidence for many of his claims against the president. And he just testified again on Wednesday, in a closed-door session with the House Intelligence Committee that Rep. Jackie Speier characterized as “explosive.”

According to CNN, all of this is enraging Trump, who is so obsessed with Cohen that it is distracting him from basic presidential duties:

The President’s aides and allies say he has raised Cohen constantly over the past week, inserting questions and complaints about him into briefings and meetings on otherwise unrelated matters. Sources say Trump has become so consumed by Cohen and the fallout from his testimony that he brings him up minutes after national security briefings, during calls with lawmakers and while strategizing with aides about administration priorities.

Trump has tweeted about Cohen almost every day for the past week and complained about him to reporters as he prepared to depart to survey tornado damage in Alabama. He also apparently is furious that Democrats held one of the Cohen hearings during his summit with North Korean dictator Kim Jong Un in Hanoi.

The president also claimed that Cohen was “begging” him for a pardon, which would appear to be a direct denial of statements by Cohen’s legal team that it was Trump who had been “dangling” a pardon before he left the joint defense agreement.

For months now, Trump’s chief preoccupation has been with special counsel Robert Mueller’s probe of his campaign’s ties to Russia, which he has tried to claim has partisan motivations, and which he called a “witch hunt” so many times that witches actually got offended.

But as Cohen continues to provide more and more information, Trump now seems to view his former fixer as the bigger threat.
