Barbara Bush blamed Donald Trump for her heart attack, reports USA Today, citing her biographical book “The Matriarch: Barbara Bush and the Making of an American Dynasty”.

It wasn’t technically a heart attack, though she called it that. It was a crisis in her long battle with congestive heart failure and chronic pulmonary disease that hit her like a sledgehammer one day in June 2016. An ambulance was called to take her to the hospital. The two former presidents who had been at home with her that day, her husband and her oldest son, trailed in a car driven by the Secret Service. The tumultuous presidential campaign in general and Trump’s ridicule of son Jeb Bush in particular had riled her.

Afterward, Jeb, whose presidential campaign was already history, urged her to let it go, to focus on herself and have faith in the country.

Did she still consider herself a Republican?

In an interview in October 2017, she answered that question yes. When she was asked again four months later, in February 2018, she said, "I'd probably say no today."

“That was a stunning acknowledgment,” the book’s author stated.

The book was written by Susan Page, the Washington Bureau chief of USA TODAY. It will be available in early April. The author managed to interact with Barbara Bush in the last 6 months of her life and also received access to her diaries.
