Republican presidential candidate Donald Trump claimed Sunday that he's responsible for Democratic rival Bernie Sanders' recent polling surge over front-runner Hillary Clinton.
Trump, who is leading in most Republican presidential polls, said during a campaign stop in Muscatine, Iowa, that the Vermont senator rose after he attacked Clinton's husband, former President Bill Clinton, for his infidelities.
"When I hit Hillary and Bill last week — but I did the right thing — but they start saying, 'Bernie Sanders is surging, an amazing thing is happening.' I did that. I did it," Trump told his audience, adding, "This guy Bernie Sanders, give me a break. They say he's a socialist, some would say he's a communist."
