Ronald Reagan would be “appalled” by the Trump presidency, daughter Patty Davis tells the Washington Post.

In a letter written on the occasion of the anniversary her father’s June 5, 2004, death, Davis said Reagan would be “pretty horrified at where we’ve come to.”

“He would be appalled and heartbroken,” she wrote, “at a Congress that refuses to stand up to a president who not only seems ignorant of the Constitution but who also attempts at every turn to dismantle and mock our system of checks and balances.”

Davis, 65, doesn’t mention Trump by name; she does make mention of how she’d once publicly criticized another president — her father.

Davis infamously joined in demonstrations against the buildup of nuclear weapons under her father’s administrations.

“My strident protests against some of my father’s policies definitely got his attention, which was what I intended — but they also wounded him, which was not my intention.”

She was eventually able to “sit with him and tell him my regrets,” she wrote.
