A symbolic transfer of power took place on Wednesday as two former Republican presidents and the White House’s current Democratic resident congratulated Republican Donald Trump on his victory last night over former First Lady Hillary Clinton.

“We are all rooting for success in uniting and leading the country,” said President Barack Obama, who previously congratulated Trump on his victory and invited him for a Thursday meeting at the White House. Speaking from the White House Rose Garden, Obama compared being president to running a relay, saying he was now prepared to “pass the baton” onto the President-elect.

Obama praised the “smooth transition” from George W. Bush’s administration to his, saying he had “instructed my team to follow the example that President Bush’s team set eight years ago and work as hard as we can to make sure this is a successful transition for the President-elect.”

Obama wryly noted that while he and Trump had seen major disagreements over time, the same had been true of the sitting  president and his predecessor, who now have a respectful relationship. A number of friendships have emerged among the last several presidents and their families, starting when Bush 43 asked his father President George H.W. Bush and Bill Clinton to raise money and attention to help those impacted by tsunamis in Asia in 2004. Clinton has become so close to the Bush family he has even come to refer to former first lady Barbara Bush as “my mother.”

Early this morning, Bush 41 — who allegedly voted for Hillary Clinton against his party’s nominee, though a spokesperson declined to confirm the rumor — tweeted that he and his family are praying for Trump.

Barbara and I congratulate @realDonaldTrump, wish him well as he guides America forward as our next President. His family is in our prayers.

His son, George W. Bush, likewise offered praise and prayers, despite not voting for Clinton or Trump:

The junior Bush has largely kept out of the political limelight since leaving office eight years ago, saying that he did not want to cause problems for Obama. While former President Bill Clinton has reportedly not spoken to Trump, Hillary Clinton offered a gracious, if pained, call for Americans to unite behind Trump.

As President Obama put it, “Ultimately, we’re all on the same team.”
