Trump is not concerned about his son: Biographer says ‘he doesn’t have the same feelings that the rest of us have’
Donald Trump Jr. speaks to MSNBC (screen grab)

President Donald Trump's fury over the Republican-controlled Senate Intelligence Committee subpoenaing his namesake son is not primarily driven by fatherly love, a Trump biographer explained on CNN.

Pulitzer Prize-winning journalist Michael D'Antonio, author of the 2015 book Never Enough: Donald Trump and the Pursuit of Success, was interviewed on CNN by Don Lemon.

The host detailed the president acting "very defensive" about the subpoena of Donald Trump, Jr.

"Do you think that’s getting to him?" Lemon asked.

"I think what’s getting to him more than concern for his son -- and I’m not sure how concerned he really is for his son because he doesn’t have the same feelings that the rest of us have for our families -- I think he’s concerned for himself," D'Antonio replied.

"He’s very much afraid that whatever Don Jr. said the first time he testified to the same committee behind closed doors will be contradicted by his subsequent testimony," he explained.

"Today Trump Sr., the dad, referred to Trump Jr. as a good guy," Lemon noted.

"Can you imagine if all your father could say is that you’re a good guy?" D'Antonio asked. "You’re talking about your son."

"I would hope that given the opportunity my dad would have said something a little more personal about me and would have praised me in a sincere way," he added.
