President Donald Trump is making his way down Constitution Avenue with a military escort as his inauguration parade begins in Washington.

The president will review the parade from a viewing stand near the White House.

He and first lady Melania Trump are riding in the presidential limousine nicknamed "The Beast."

Trump is being cheered by supporters as his car passes.

Others are shouting "Media sucks" while a group of protesters chants, "Not my president, not my president."

Earlier Mr Trump — in brief remarks at his inaugural lunch at the Capitol — said he was honoured that Hillary Clinton, his rival in the White House race, came to the event.

The bipartisan crowd of lawmakers and other dignitaries gave Clinton a standing ovation after Trump asked her to rise.

Clinton and her husband, former President Bill Clinton, sat with members of Trump's family at the event.

Trump ended by saying he has "a lot of respect for those two people."

Mr Trump was named the 45th President of the United States at midday on Friday. His inauguration was met with protests across Washington DC.

Elsewhere, two new petitions have appeared on the White House website: one calling for an immediate "release of Trump's full tax returns", while the other one says the 45th president "should divest his financial and business holdings or have them administered by a truly blind trust".

Going back to the confirmation of retired General James Matthis, who was approved 98-1

New York Sen. Kirsten Gillibrand, who challenged the idea of a former military leader in a civilian job, voted “no.”

Republicans pushed for fast approval to ensure the post wouldn't be empty even for a brief amount of time after Mr Trump's swearing-in. 

Mr Mattis will replace Ash Carter, who has been former President Barack Obama's defense secretary since February 2015. 

Congress had to pave the way for Mr Mattis to serve. Legislators passed legislation last week that Mr Trump signed granting Mr Mattis an exception from the law barring former service members who have been out of uniform for less than seven years from holding the job. 

Mr Mattis retired from the Marine Corps in 2013.

Donald Trump has apparently not been into the Oval Office yet, so the letter from outgoing President Barack Obama is probably still waiting to be read.

A second of Mr Trump's Cabinet picks has been confirmed.

The US Senate voted overwhelmingly to approve retired Marine General John Kelly as Secretary of Homeland Security.

Eighty-eight senators approved Kelly and just 11 opposed him. One senator did not vote.

That news comes as the three inaugural balls in honour of the Trumps are going to get started soon - with them due to begin in about 15 minutes.

Mr Trump will speak at all three events, and the President and the First Lady will dance at all three events. Their first dance will be to the Frank Sinatra hit 'My Way'.
