Donald Trump's record-breaking £74m donation haul for inauguration

With £74m of private donations so far, Donald Trump's inauguration has proved to be an attractive way for corporations to set out their stall for America's next commander-in-chief.

Mr Trump's inauguration committee has received enough money to pay for the event twice over - and the money is still flowing in.

Most donors remain anonymous and the committee has 90 days to name them.

Blue chip donors named so far include aircraft maker Boeing, which has donated £820,000.

The company's multibillion-dollar Air Force One contract was last month threatened with cancellation by Mr Trump.

Oil and gas giant Chevron has donated £410,000 while AT&T has supplied extra mobile capacity for the National Mall.

US taxpayers will provide a considerable share of the budget despite a big share of the inauguration costs being covered by the private donations.

Public funds will pay for the £4.1m cost of building a bunting-decorated 10,000 square-foot platform for the swearing-in.

The public also pays security costs for the event, which brings together a big chunk of the US political leadership, hundreds of thousands of ordinary Americans and a fair share of protesters.

This will include a £2m overtime bill for the US Capitol police force. Federal funds will also pay for more than 5,000 service members from across the regular armed forces, plus a further 7,500 National Guard reservists.

The District of Columbia expects to spend £24m, which it will claw back from federal government after the event.

This leaves an unprecedented and unspent pot of private donations for Mr Trump's inauguration team to spend on pop singers, parades, choirs, celebratory balls, bunting - and more than 1,000 portable toilets.

The man who organised America's last two inaugurations has questioned why donors' money is still coming in and wondered where it will go.

"We planned the two largest inaugurations in the history of our country and we never spent anywhere near that," said Steve Kerrigan, who led Barack Obama's 2009 and 2013 inauguration events.

"I can't imagine how they are going to spend that amount of money - and why they would even keep raising money," he said.

Mr Kerrigan's committee collected £45m for Mr Obama’s first inauguration and £35m for his second.
