swear in

Last year, Verstappen was ordered to do a form of motorsport community service after swearing in a news conference at the Singapore Grand Prix.

The New York mayor met with Trump in Florida days before his inauguration, and then attended his swearing in ceremony on 20 January.

Throughout Washington, flags that were at half-staff following the death of former President Jimmy Carter were returned to full height for the swearing in.

Trump said his swearing in ceremony on Monday would end what he called "four long years of American decline" and bring "a brand new day of American strength, prosperity and pride".

A spokeswoman for Butler said she will remain in office until the swearing in.
