Donald J. Trump fired his wunderkind campaign manager Corey Lewandowski Monday at the campaign’s regular Trump Tower meeting.

“Corey was escorted out of the building,” a source close to the campaign told Breitbart News.

Lewandowski came to the meeting unaware that he had lost the support of the GOP presumptive nominee, the source said. At the meeting, attended by both senior campaign staff and members of the family, Trump reviewed different campaign metrics that were all faltering: cooperation with party leaders, fundraising, surrogate operations and most importantly the polls.

The campaign manager seemed to have run out of ideas. When the New York City developer asked Lewandowski what he would do to turn things around, the only thing he could come up with was for Trump to announce his pick for vice-president.

Pitching that as the solution sealed his fate, the source said. “The VP pick was the one piece of suspense that would make people tune into the convention—Corey wanted to give that away now? There was no way.”

When the time came for Trump to lower the axe, no one spoke up to defend Lewandowski.

One month ago, Lewandowski was reported in the New York Post to have had a screaming match with the campaign’s press secretary about the running of the campaign on an uptown Manhattan street four blocks up from Trump Tower.

Afterwards, there was speculation that Lewandowski was in trouble.
