'I think he's scared': Trump biographer calls Trump caving into Nancy Pelosi 'shocking'

Researcher and writer Michael D'Antonio thinks that President Donald Trump is getting "scared."

In a conversation with CNN, the Trump biographer listened as host Don Lemon read the president's tweet caving into Speaker Nancy Pelosi's hold on the State of the Union.

"Have you ever heard this president write something like that?" Lemon asked. "It seems like a normal presidency."

"It's shocking," D'Antonio said. "This sounds like something that maybe Ivanka wrote or Jared Kushner. It really doesn't sound like Donald Trump's language. This is a fellow who has troubles stringing three words together in the right order."

D'Antonio noted it's also respectful, which isn't exactly Trump's style. Lemon asked what it meant his guest had a shocking assessment.

"I think he's scared. He's afraid," the biographer continued. "He's politically afraid the Senate Republicans are probably telling him this is a disaster. He sees that people are suffering and are fed up with maybe he's going to act presidential because he's being forced to act presidential."
