President Joe Biden and first lady Jill Biden will attend Donald Trump’s inauguration in January, a White House spokesperson said on Monday.

“The president promised that he would attend the inauguration of whomever won the election,” said Andrew Bates, senior deputy press secretary at the White House, Reuters reported.

“He and the First Lady are going to honor that promise and attend the inauguration.”

The president-elect did not attend Biden’s inauguration in January 2021, which came days after the January 6 attack on the US Capitol.

Earlier this month, the US president welcomed Trump back to the White House – another tradition Trump eschewed after losing the 2020 election- with Biden promising a transfer of power that is “as smooth as it can get”.

“We’re looking forward to having, like we said, a smooth transition. We’ll do everything we can to make sure you’re accommodated, what you need, and we’re going to get a chance to talk about some of that today,” Biden said earlier this month. “Welcome back.”

Trump’s decision to skip Biden’s inauguration was not without precedent, but he was the first president to skip his successor’s inauguration in more than 150 years and his then outgoing administration was represented by then outgoing vice-president Mike Pence.
