BUENOS AIRES — President Donald Trump and first lady Melania Trump will attend a funeral service for the late President George H.W. Bush at Washington’s National Cathedral, White House press secretary Sarah Sanders said Saturday.

While the Trump and Bush families have had their differences — the former president’s son Jeb was one of the candidates dispatched by Trump in the 2016 Republican presidential primary — the death of the Bush family patriarch brought kind words from Trump, who in a late-night statement called him a “truly wonderful man.”

Sanders said the Trump administration is working to arrange a state funeral for Bush and that the president will declare Dec. 5 a national day of mourning in his honor.

Trump was expected to speak by phone with former President George W. Bush, another son of the deceased president, Saturday morning.

He did not attend a funeral for former first lady Barbara Bush earlier this year.
