Hillary Clinton has agreed to attend the swearing-in ceremony of her Republican opponent President-elect Trump later this month, following widespread speculation that she and former President Bill Clinton would skip the inaugural activities.

Aides to the defeated Democratic presidential hopeful and ex-president told multiple outlets on Tuesday that both will be in attendance for Trump's inauguration on Jan. 20. The report came less than an hour after former President George W. Bush and his wife, Laura, announced that they both plan to attend the ceremony.

Clinton suffered a bruising defeat in the November election that few saw coming and has kept a low profile, with the exception of previously scheduled public speaking engagements, since delivering her concession speech on Nov. 9. The former secretary of state and her husband maintained a personal relationship with the president-elect and incoming first lady Melania Trump in the years leading up to 2016, though their friendship quickly dismantled over the course of the election cycle. Trump and Clinton exchanged sharp barbs during their one-on-one debates and sought to paint each other as corrupt and unfit to serve as commander-in-chief.

In the two months since Trump's victory, Clinton backed vote recounts in a trio of battleground states she lost and urged intelligence officials to brief electors on Russia's cyberactivity ahead of the Electoral College vote on Dec. 19.

The Clintons' decision to attend the inauguration leaves George H.W. Bush as the only living ex-president who has yet to confirm his participation in the upcoming inaugural activities.
