MSNBC's Mika mocks Trump for lying about his dad: 'You're a birther! How do you not know where your parents were born?'

MSNBC's Mika Brzezinski tried to make sense of President Donald Trump's inaccurate claim that his father was born in Germany -- something he has said many times before.

The "Morning Joe" co-host rolled a series of video clips showing various times the president has misrepresented the birthplace of his father Fred Trump, who was born in the Bronx in 1905.

"You're a birther -- how do you not know where your parents were born?" Brzezinski said. "How can you get that wrong so many times? I'm just -- it's vexing."

Brzezinski asked the other panelists if they had an explanation for Trump's odd claims.

"I was born in Germany, so I can speak to this," deadpanned author Mark Leibovich. "No, I mean, it is curious. It is not kind of a standard variety lie, necessarily. What do you gain from it?"

"He has these asides," Leibovich continued. "'I'm German, my father was German.' Something you can drop into a conversation. It's almost as if he wants it lyrically, the phrase, to include a kind of, you know, falsehood in a weird way. I don't know, I don't quite know where it gets him or what he is trying to do."

MSNBC contributor Elise Jordan said it was one of the many bizarre tics the president exhibited on a daily basis.

"I don't think we've ever seen anyone on the world stage with such a five-minute window of attention span," she said, "where if he thinks in the moment saying his father was German, a blatant lie, is going to gain him praise, he'll do it."
