The Fox News host created a sensation at two campaign events today.

At a Barack Obama rally in Nashua, N.H., he got into a confrontation with an Obama aide while trying to get a good view of the presidential candidate at a rope line.

Many members of the press were not aware that O’Reilly was even there — until he got into a scuffle with Obama’s trip director, Marvin Nicholson.

to CBS News’ Maria Gavrilovic, news photographers said that O’Reilly was “shouting and pushing Nicholson,” demanding that he get out of the way of his camera crew’s view of Obama.

“I don’t know exactly what happened”, Nicholson said, “I was shadowing the Senator as I often do during the rope line and he started yelling at me to move out of the shot.

According to Nicholson, O’Reilly was told to go back behind the barricade. Nicholson then approached O’Reilly.

“I went up to him and said ‘Sir, don’t push me anymore,’” Nicholson said, “and he said that I was low class.”

In a phone interview on Fox News this afternoon, O’Reilly said that he asked Nicholson “fairly nicely, ‘You are blocking the shot sir.'” When Nicholson didn’t, “I had to gently remove him from that position.

O’Reilly said there was “no scuffle at all. I just removed him from the camera range.”

Asked whether he shouted at Nicholson, O’Reilly said, “I might have called him an SOB.”

“We are sorry we had that confrontation, but no one on this earth is going to block a shot by the O’Reilly Factor. It is not going to happen.”

He did, in the end, talk to Obama, which he said he would elaborate on more on Monday’s “O’Reilly Factor.”

According to CBS, Nicholson said that O’Reilly told Obama how much he loved him and how great he was.

One reporter asked, “Did he say ‘love”?”

Nicholson coyly replied, “I’m not sure, the sentiment was love.”

Earlier, O’Reilly attended a Hillary Clinton event, where she actually greeted him from the stage once that it was pointed out to he that he was in the audience.

“Oh, hi Bill!” she said. “Give that man points for courage.”

O’Reilly later said, “We did get an interesting back and forth from her on the stage to me, which was fine.”
