Washington, May 2 (IANS): Republican front-runner Donald Trump denounced Democrat Hillary Clinton's recent comments about being familiar with "men who sometimes get off the reservation", calling the remarks "demeaning to men".

"I thought it was a terrible answer," Trump said on 'Fox and Friends' on Sunday.

"She said, 'I am used to dealing with' -- and what was the word? Go ahead, she used a certain word. 'Men off the reservation.' And I said to myself that's a horrible expression."

The billionaire was responding to remarks the Democrat front-runner made in a CNN interview last week.

Asked how she planed on handling Trump's attacks of her on the campaign trail, Clinton dismissed them, saying, "I have a lot of experience dealing with men who sometimes get off the reservation in the way they behave."

Some activists took to Twitter shortly afterwards slamming Clinton on the phrase "off the reservation" as offensive to Native Americans.

Later, Clinton's national political director, Amanda Renteria, apologized on social media for the phrase's "offensive roots".

Trump, who has repeatedly trashed the notion of political correctness on the campaign trail, piled on to the criticism.

"If I would have used that expression -- maybe in the opposite form -- it would have been a front page story. She uses it and gets away with it," he said, adding "That's a very demeaning remark to men in my opinion."

Then he suggested, "Was she referring to her husband? I think she was referring to her husband."
