President Trump’s return to the White House on Monday was a historic political comeback.

Before frigid temperatures in Washington forced officials and revelers inside, nearly 150 news photographers were lined up to document what would have been an outdoor ceremony at the Capitol. Eight news photographers were allowed in the Rotunda, but the New York Times photographer Doug Mills was the only one who captured Mr. Trump’s entire day on camera.

Here is a look at the first day of Mr. Trump’s second term, in nine images:

7:45 A.M.

The day began at church.

Mr. Trump, Vice President JD Vance and their families started the day with a traditional service at St. John’s Church. The building, across from Lafayette Square in downtown Washington, is near the White House and known as the Church of the Presidents because every leader since James Madison has attended worship there.

9:54 A.M.

The Bidens welcomed Trump to the White House.

After the church service, the Trumps headed to the White House, where they were greeted by the departing president, Joseph R. Biden Jr., and the first lady, Jill Biden.

“Welcome home,” Mr. Biden told them as they arrived, observing the rituals of the day for his predecessor, who refused to concede the 2020 election or attend his inauguration four years ago. By contrast, Mr. Biden hosted Mr. Trump for coffee before the inauguration ceremony.
