The Republican National Convention has kicked off with a roll call formally nominating Donald Trump to run in the 3 November election.
How will the four-day event unfold?
Let's back up first.
There's an obvious question…
What is the Republican National Convention?
OK, good question.
Party conventions take place once every four years – they are the ceremonial crowning of the party's presidential candidate as they prepare for the final phase of campaigning.
Last time around, we saw the Trump family take centre stage to a backdrop of fireworks and a sea of red, white and blue balloons.
It's also where party officials wrap up other less-glamorous business, like unveiling the political platform and adopting rules. This time – for the first time – no new platform is being adopted – the party will continue to support Mr Trump's 2016 manifesto.
As the sitting president, Mr Trump is the de facto nominee. But the convention has formally nominated him with a roll call, nonetheless.
On Thursday, the president will formally accept the nomination with a big speech.
How is the Republican National Convention being held this year?
The conventions of years past have been glitzy affairs, bringing together thousands of delegates, party leaders, activists and celebrities for receptions, speeches and general hyping up of the presidential candidate.
But the pandemic has upended all that.
Unlike its Democratic counterpart, the Republican Convention is hosting some in-person business.
But people are being told they need to wear masks and social distance. Those attending are given a self-swab Covid-19 test before travelling and entering their hotels.
OK, so where will Trump be?
He will accept the nomination in a "real speech on Thursday", live from the White House.
This hasn't been entirely well-received – with critics arguing using federal property for a campaign speech is unethical.
Who is speaking on Tuesday night?
Headlining is the first lady but the appearance of the secretary of state has raised eyebrows as the office is meant to be above or separate from getting involved in political campaigning.
- First Lady Melania Trump
- Eric Trump
- Tiffany Trump
- Secretary of State Mike Pompeo
- Senator Rand Paul
- Nicholas Sandmann, who featured in a viral video last year with a Native American veteran in front of the Lincoln Memorial in the nation's capital
Who are the other speakers this year?
- Vice-President Mike Pence and wife Karen
- Eric Trump's wife Lara
- White House adviser Kellyanne Conway
- President Trump
- Senate Majority Leader Mitch McConnell
- Ivanka Trump
- Alice Johnson, a criminal justice reform advocate whose life sentence was commuted by the president after a campaign led by Kim Kardashian
- Parents of Kayla Mueller, an American aid worker who was taken hostage and killed in Syria
Mr Pence will accept his running mate role from Fort McHenry in Baltimore. It's a place heavy with historical significance, because it is where US soldiers withstood the might of the British in 1814, inspiring Francis Scott Key to write the poem that became the national anthem.
Like its Democratic counterpart, the Republican programme will also be a mix of pre-recorded and live speeches, based in Washington DC.
Each day will follow themes of America as the land of promise, opportunity, heroes and – in a nod to Trump's slogan – greatness.
What time is the Republican National Convention?
The convention is expected to last 2.5 hours each night, Monday to Thursday, from 20:30 EST (00:30 GMT) to 23:00 EST (03:00 GMT).

Three things to watch out for
Few incumbent presidents of the modern era have faced a challenge as great as the one before Donald Trump in the final months of their re-election campaign. He has consistently trailed Joe Biden in the polls by a modest but significant margin for months. The Republican Convention is one of his last, best opportunities to turn the tide.
The coronavirus pandemic has made a traditional convention format impractical, but it appears the Republicans will try to come close to replicating the feel of one. Unlike the Democrats, they will have audiences for many of their speeches, including Donald Trump's Thursday night address, which will be held from the South Lawn of the White House.
That speech will be a good guide for how the Republicans hope to conduct their campaign over the final months. Will he focus on tearing down Joe Biden or on accomplishments from early in his presidency? Or will he try to convince the public that the worst days of the pandemic are over?
The Democrats during their convention turned to voices from "ordinary" Americans – immigrants, workers and minorities – who said they Read More – Source
