Trump's most 'feral belief' stuns presidential historian

Presidential historian Douglas Brinkley was stunned on Tuesday as President Donald Trump unveiled his "feral belief" about the presidency during a rambling speech.

Trump gave a more than 80-minute monologue during the White House press briefing to mark the anniversary of his first year in office. At one point, he said his public relations team was not doing a good enough job of selling his accomplishments in office, like how Immigration and Customs Enforcement officers are deporting people to third countries and his efforts to annex Greenland.

Brinkley discussed Trump's speech on CNN's "The Lead" with Jake Tapper on Tuesday, and argued that Trump exposed his "feral belief" that his power is unlimited.

"I'm not surewhere he put points on theboard," Brinkley said. "I don't think it was a great recap of his first year, but it reminds us, Jake, that really the year has been known about Trump being ubiquitous and that his feral belief that his presidential powers are unlimited."

Trump has sought to dramatically expand presidential power during his second term. He has threatened to invade allies like Canada and Greenland, and ordered an operation to capture Venezuelan dictator Nicolás Maduro and his wife, Cilia Flores, without Congressional approval.

Trump has also unilaterally imposed tariffs on U.S. trading partners, a move that the Supreme Court is expected to weigh in on soon.
