Donald Trump and Melania Trump are attending George H.W. Bush’s funeral, but according to Douglas Brinkley, a presidential historian who knew George H.W., he was only invited because the Bush family didn’t want to “stiff a sitting president.” 

“For Bush 41, Trump is the president, and he does not want to stiff a sitting president,” Douglas told People. “So in his own way, it is magnanimous that he is having Melania and Donald Trump come.” He added, “In its own way, it may normalize the estrangement Trump feels from the so-called establishment that Bush personified.” 

As far as George H.W.’s opinion on the Trump administration, Douglas said, “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.”
