Ivanka Trump said Monday her father is "level-headed" and defended his campaign tactics, while at the same time taking a shot at his critics.

"He's incredibly level-headed. I think that he fights and he's strong. He's has to fight. He has a lot of people coming at him," Ivanka Trump told the Detroit Free Press. "He also has tremendous support and love and enthusiasm for his positions."

Trump said her father was the last man standing in a field of 17 Republican candidates for president, so "it's not my place to tell him to change his campaigning style."

Regarding her father's critics, Trump said, "they're scared. They never thought that he'd be where he is.

"I think there will be many people who will seek to diminish him."

Donald Trump has come under fire in recent weeks from several fronts, and some polls now show he has lost ground to Democrat Hillary Clinton.
