President-elect Donald Trump’s inaugural committee on Wednesday said he plans to attend a private family church service at St. John’s Episcopal Church near the White House the morning of the Jan. 20 inauguration.

Trump also will likely be staying at the Blair House the night before he is sworn in as the country’s 45th president, according to Alex Stroman, a spokesman with the committee. For the past 40 years, every president-elect has stayed at the Blair House near the White House before Inauguration Day, though it was unclear if Trump would choose to stay there or at his luxury eponymous hotel nearby.

The Presidential Inaugural Committee said it is working on additional details of an extensive five-day schedule of events beginning the Tuesday before inauguration. So far, most of the festivities are in keeping with tradition.

The official inauguration ceremonies are set to launch with the president-elect and Vice President-elect Mike Pence laying a wreath at Arlington National Cemetery Thursday, Jan. 19, the committee announced. That will be followed by a welcome concert at the Lincoln Memorial. The events will conclude with a National Prayer Service at the Washington National Cathedral on Saturday, Jan. 21.

“President-elect Trump is committed to unifying our country as we once again celebrate the foundation of our American system and the peaceful transfer of power,” Presidential Inaugural Committee Chairman Tom Barrack wrote in a release.

The committee said the events surrounding the inauguration will include dinners honoring Trump, Pence, cabinet secretaries and more. The committee has not yet released details about these events.

Officials with the inaugural committee have announced that Jackie Evancho, a 16-year-old former “America’s Got Talent” contestant, is set to perform the national anthem. The committee is planning a welcome rally, two official inaugural balls and a ball for military families, veterans and first responders. The theme of the inauguration, according to the committee, will be “Make America great again!”

Federal and city officials say they expect upward of 800,000 people to attend inauguration and the parade. More than 13,000 members of the military and National Guard are expected to be in downtown Washington on inauguration, providing security and participating in the parade and ceremonies. D.C. police, the Secret Service and U.S. Capitol Police will also be working.

There is a larger number of demonstrators than usual this inauguration, with more than 15 groups applying for “First Amendment” permits through the National Park Service, according to the federal agency that manages the country’s parks.
