"President Bush would never — under any circumstance — intentionally cause anyone distress, and he most sincerely apologises if his attempt at humour offended Ms. Lind," Jim McGrath, a Bush spokesman, told HuffPost in a statement on Wednesday.
Later on Wednesday, Bush's office issued a second statement saying that the former president "has patted women's rears in what he intended to be a good-natured manner" and that because he is confined to a wheelchair, "his arm falls on the lower waist of people with whom he takes pictures."

In a now-deleted Instagram post on Tuesday, Lind said she posed with Bush, who was in a wheelchair, for a photo-op during a private screening in Houston of her AMC television series, "Turn: Washington's Spies." "He sexually assaulted me," she wrote in the post, according to reports.
"He didn't shake my hand," Lind wrote. "He touched me from behind from his wheelchair with his wife Barbara Bush by his side. He told me a dirty joke. And then, all the while being photographed, touched me again. Barbara rolled her eyes as if to say 'not again.' His security guard told me I shouldn't have stood next to him for the photo."
Lind said she has learned to use her own personal power against those who wield theirs inappropriately. "It seems to me a president's power is in his or her capacity to enact positive change, actually help people, and serve as a symbol of our democracy. He relinquished that power when he used it against me and, judging from the comments of those around him, countless other women before me. What comforts me is that I too can use my power, which isn't so different from a president really."
Lind said she was moved to recount the experience after seeing a photo of the 93-year-old Bush with former President Barack Obama at the One America Appeal hurricane relief concert. She said she was disturbed that Bush was afforded such reverence.
Lind's accusation follows a slew of recent public sexual harassment and assault allegations against film executive Harvey Weinstein, director James Toback and others.
