Donald Trump Jr. cites James O'Keefe and says his dad will only concede if results are 'legit'

Donald Trump Jr. said on Tuesday that he expected his father to concede if "legit and fair" results showed that the Republican nominee lost to Democratic opponent Hillary Clinton.

In an election day interview, MSNBC host Willie Geist reminded Donald Trump Jr. that his father had said for months that the election was "rigged."

"Can you say here right now, if Hillary Clinton is a clear cut winner tonight in the Electoral College, your father will concede the election in a speech tonight?" the MSNBC host wondered.

"Of course," Donald Trump Jr. insisted. "All we've wanted is a fair fight."

Citing undercover videos by discredited conservative filmmaker James O'Keefe, the younger Trump suggested that Democrats may be using dirty tricks to steal the election from his father.

"You know, we just want a fair system," he said. "Some stuff is going on. I don't know if it's enough to move elections. But we've seen states, you know, a few thousand votes can make a difference."

Geist pressed: "If he loses, he will concede tonight?"

"If he loses and it's legit and fair," Donald Trump Jr. replied. "Without question, yes."
