Former President George W. Bush and former first lady Laura Bush will attend president-elect Donald Trump's inauguration Jan. 20, according to a statement from the former president.

"They are pleased to be able to witness the peaceful transfer of power — a hallmark of American democracy — and swearing-in of President Trump and Vice President [Mike] Pence," Bush's spokesman Freddy Ford said in a written statement.

No other information was released.

Bush will not be the only former president in attendance. According to Politico, former President Jimmy Carter, 92, also announced he will attend.

But a spokesman for Bush's father, George H.W. Bush, told Politico the 92-year-old 41st president will not be attending the inauguration, citing his age as the reason why he was skipping the event.

The relationship between Bush and Trump has been complicated. George W. and Laura Bush did not vote for either Trump or former Secretary of State Hillary Clinton, instead voting for Republicans down ballot. George W. Bush and his father sat out the 2016 general election campaign.

But after Trump's surprising victory, Bush released a statement saying he had called Trump and congratulated him on his election.

Shortly after Bush's announcement, aides to Bill and Hillary Clinton confirmed to The Hill that they would also be attending Trump's inauguration.
