"My mother had been in poor health for quite a while, and recently had gotten markedly worse, so this wasn't a surprise," she said.
The statement sparked surprised responses, with one report calling it “terse.” Patti has since responded to their criticism.
“To the people who called my short piece on my website 'terse,' perhaps you haven't experienced how overwhelming it is to lose a parent,” she said. “It's shameful that people would find fault with that, but then 'the haters are going to hate.'”
Nancy Reagan passed away from congestive heart failure. Her funeral will be held on Friday and she will be buried alongside her husband at the Reagan Library in California.
Bill O'Reilly, who wrote the bestseller "Killing Reagan," told INSIDE EDITION that she was a hero for the decade she spent caring for her husband after he was diagnosed with Alzheimer's.
“I dedicated the book to all the people who care for the elderly, based on what she did,” he said.
The Fox News host said Nancy became ferociously protective of President Reagan after he narrowly escaped assassination in 1981.

“You could not get to Ronald Reagan unless you went through Nancy Reagan,” he said. “She was the gatekeeper and that was it.”
O’Reilly remembered the last time he spoke with her.
“She was with it,” he said. “She followed events, but she stayed quiet, to herself. She had her circle of friends and once her husband died, she was looking forward to seeing him again in heaven.”
