A lawyer for two nurses who claim they were physically abused by Robert F. Kennedy's son Douglas Kennedy in a tussle over an infant said they are likely to sue as two new witnesses came forward to back up their story.
Attorney Elliot Taub said the new witnesses will corroborate his clients' version of the Jan. 7 confrontation. A lawsuit against Kennedy is likely, he added.
The nurses allege Kennedy twisted one's wrist and kicked the other while they tried to prevent him from taking his 2-day old son from the maternity ward at Northern Westchester Hospital in New York.
Kennedy has said he was taking his baby, Beau, out for some fresh air when nurses tried to stop him from getting on the elevator. So he headed to the stairs, where he was blocked again.
A confrontation ensued.
Surveillance video appears to show Kennedy in a violent scuffle with two nurses.
On the video, Kennedy can be seen lifting his leg, and then a nurse falls backwards onto the floor.
In court documents obtained by ABC News, nurse Cari Luciano claims Kennedy attacked her.
"As my hand touched the shoulders of the baby, Douglas Kennedy, raised his right foot, and with tremendous force, kicked me in the left side of my pelvic area," Luciano said, according to the documents.
The nurse claims she called two alerts: code pink, child abduction in progress, and code purple, a combative party.
Kennedy was arrested by Mount Kisco police on misdemeanor charges of child endangerment and harassment relating to the incident. He has pleaded not guilty.
The nurses' attorney says his clients' actions were by the book.
"They did their job, did a darn good job, were violated, injured and now you have people … casting blame on them. Shame. It's disgusting," he said.
Nurses are trained to prevent people taking newborns from the ward without permission since people who try to abduct babies are often family members, Taub said. Kennedy had no reason to lash out, Taub added.
Robert Gottlieb, Kennedy's lawyer, has said the nurses lunged at his client while he was holding his newborn child and he had to protect the child.
In response to that claim, Taub replied: "I can see readily while he's out of the scope of the video, very carefully orchestrated with nice lawyer spin, to put this in a position where you can't see it on video, so now you can come forward with any scenario you want."
The two new eyewitnesses are fellow nurses who will support his clients, he said, adding that there could be further evidence showing Kennedy may have exhibited unusual prior behavior on the ward, although Taub offered no proof to back up that claim.
"Ask anyone in this country," he said. "Ever heard of a 2-day-old being taken outside for fresh air? That's reckless, it's nonsense. It's stupidity."
But Gottlieb rejects that claim.
"He did nothing wrong," Gottlieb said of Kennedy's actions on the ward. "He's a loving father who with his healthy baby boy, with the knowledge and participation of the mother, Molly, simply wanted to take his child outside for some fresh air. What is possibly wrong with that?"
Gottlieb said he believes the nurses pressed charges because they want money.
The hospital has issued a statement in support of the nurses, but Dr. Timothy Haydock - an on-duty doctor at the hospital and Kennedy friend who witnessed the incident - said Kennedy did nothing wrong and the nurses were the only aggressors.
