PresidentDonald Trumpand First LadyMelania Trumpplan to attendGeorge H.W. Bush‘s funeral — and according to a presidential historian who knew Bush, the former president included Trump in order to not “stiff a sitting president.”

“For Bush 41, Trump is the president, and he does not want to stiff a sitting president, so in his own way, it is magnanimous that he is having Melania and Donald Trump come,” Brinkley says of Bush, whodied at age 94 on Friday.

Brinkley believes that Bush’s wishes may affect Trump, 72, personally. “In its own way, it may normalize the estrangement Trump feels from the so-called establishment that Bush personified,” he adds.

Brinkley suggested that Bush had mixed feelings about the Trump era. “I think that [Bush] had such respect for the institution of the presidency that Trump annoyed him because he was trying to divide the country at times,” Brinkley tells PEOPLE.

“He is a fine husband, father, and friend — and a man of the highest integrity. He will make a superb Justice of the Supreme Court of the United States,” George W. Bush previously said.
