WASHINGTON President-elect Donald Trump again denied mocking a reporter for a physical disability in a series of tweets on Monday, even though he clearly appears to have done so while on the campaign trail in 2015.

Trump was responding to actress Meryl Streep , who criticized the incoming president in a speech at the Golden Globes on Sunday.

In fact, video appears to show Trump imitating New York Times investigative reporter Serge Kovaleski, who has arthrogryposis, a disease that limits the function of his joints . At a South Carolina rally in November 2015, Trump jerked his arms and said , Now, the poor guy, you ought to see this guy, Ah, I dont know what I said, I dont remember, I dont remember, maybe thats what I said.

Trump went after the reporter whom he also called nice because Kovaleski denied that a story he co-wrote in 2001 substantiated Trumps claim that thousands of people in New Jersey cheered the fall of the World Trade Center. No evidence supports Trumps claim .

The sad part about it is, it didnt in the slightest bit jar or surprise me that Donald Trump would do something this low-rent, given his track record, Kovaleski said after the incident . Kovaleski declined to comment Monday.

Since facing criticism over his behavior, Trump has repeatedly tried to backpedal. He claimed that he did not know what the reporter looked like Kovaleski has, in fact, closely covered Trump in the past and was merely mocking the fact that the reporter was trying to pull away from a story.

Last year, Trump said that he would never mock a person with a disability because he spends millions a year, or millions of dollars on ramps, and get rid of the stairs and different kinds of elevators all over. Federal law actually requires Trump to make his buildings accessible to Americans with disabilities.

Streep said on Sunday, it kind of broke my heart when I saw it, and I still cant get it out of my head, because it wasnt in a movie. It was real life. She later added, When the powerful use their position to bully others, we all lose.

On Twitter Monday, Trump responded by calling Streep, a three-time Oscar winner , one of the most over-rated actresses in Hollywood.
