He also sought an apology from New York Times which earlier issued a statement condemning him for ridiculing its reporter.
Donald during his South Carolina rally on Tuesday allegedly mocked a reporter of New York Times.
Trump allegedly mocked NYT reporter Serge Kovaleski's physical condition; who has arthrogryposis, which visibly limits flexibility in his arms.
"I do not know the reporter for the @nytimes, or what he looks like. I was showing a person groveling to take back a statement made long ago!" tweeted Donald Trump.
"Now, the poor guy - you've got to see this guy, 'Ah, I don't know what I said! I don't remember!' " Trump said as he jerked his arms in front of his body.
In a statement Thursday, Trump adamantly denied that his comments or gestures were meant to mock Kovaleski. He also denied remembering Kovaleski at all - "despite having one of the all-time great memories,"reported NDTV.
"Kovaleski must think a lot of himself if he thinks I remember him from decades ago - if I ever met him at all, which I doubt I did," Trump said. "He should stop using his disability to grandstand and get back to reporting for a paper that is rapidly going down the tubes."
