Inauguration security

Security ramping up ahead of Trump inauguration

Mr Trump has arrived in the US capital and begins a weekend of official events, starting with a lunch with his incoming cabinet and formal wreath-laying at the Arlington cemetery ahead of his swearing in.

Police have forecast that about 900,000 people, both supporters and opponents, will flood Washington for the inauguration ceremony.

The ceremony on Friday (Saturday morning NZT) includes the swearing in on the steps of the US Capitol and a parade to the White House along streets thronged with spectators.
