President Trump decorated the Oval Office with a collage of family photos and other personal effects that were on full display during his first day back in the White House.

The rug, which was in place during Ronald Reagan’s administration and during Trump’s first term, was reinstalled during Trump’s inauguration ceremony, according to CBS News. The Resolute Desk had to be partially disassembled in order to facilitate its return.

President Trump was eager on Monday to point out contrasts with his Democratic predecessor, including a free-wheeling Oval Office press conference.

"Maybe we should all read it together," Trump told reporters upon finding Biden's letter. "Maybe I'll read it first and then make that determination."

Fox News Channel host Sean Hannity will present an interview with President Donald Trump from the Oval Office on Wednesday at 9 p.m. ET. The "Hannity" exclusive sit-down will be Trump’s first Oval Office interview since returning to the White House.

Another return to the Oval Office in Trump 2.0 is a sculpture called “The Bronco Buster” by artist Frederic Remington, which sits under the portrait of Jackson.

Joe Biden’s blue rug was swapped for Trump’s neutral-coloured one as part of a switch from the outgoing president’s belongings to the incoming one’s, and Trump’s infamous red Diet Coke button reportedly was back in place by as early as mid-afternoon on inauguration day.

The revamped White House Oval Office will once again feature the Diet Coke button that President Trump used to summon sodas during his first term. The famous little red button, hidden inside a wooden box, was spotted on Trump’s resolute desk after his inauguration ceremony on Monday, according to the Wall Street Journal.

Donald Trump moved quickly after returning to the White House to reinstate a bust of Britain’s Second World War Prime Minister Sir Winston Churchill in the Oval Office, a move he also made in 2017.

Every president since Ronald Reagan has left a note for his successor, and President Biden is the first to write a letter to someone who is both his successor and the predecessor who left a note for him.

When pressed on Inauguration Day about what he had written to the incoming president, Biden said “That’s between Trump and me."
