Who just called Donald Trump 'boring'?

Republican presidential front-runner Donald Trump's campaign has been marked by a number of controversies.

New York: Donald Trump ejected a man from a rally after he called the Republican presidential front-runner "boring", an incident that comes close on the heels of a Muslim woman's removal from his campaign event for protesting silently.

The man interrupted Trump's speech in Windham, New Hampshire, yesterday with three words that struck at the core of the presidential aspirant's brand.

"This is boring," a man standing near Trump shouted at the candidate who just two days earlier embraced a comparison to the famous showman PT Barnum.

After pausing briefly to take in the man's words, Trump called for the man to be ejected.

"Get him out of here," Trump shouted. The man, wearing a "Make America Great Again" had, insisted that he was a Trump supporter as he was escorted out, CNN reported.

"I love Donald but it's getting a little boring," the man said. "It's getting a little boring."

The incident comes after a Muslim woman wearing a hijab was escorted out of Trump's campaign event in Rock Hill, South Carolina last week by police after she stood up in silent protest during Republican presidential front-runner's speech.

Rose Hamid, a 56-year-old flight attendant, sitting in the stands directly behind Trump, stood up during his speech when the Republican front-runner suggested that Syrian refugees fleeing war in Syria were affiliated with ISIS.

Despite her silence, Hamid and the man alongside her who stood up as well were escorted out. Trump's campaign has been marked by a number of controversies from his call for a temporary ban on Muslims entering the US to his alleged mocking of a journalist's physical disability.
