Singer Lady Gaga will be heading to Pittsburgh tonight to join Joe Biden at a drive-in event - and some in the Trump camp are clearly unhappy about it.

Communications director Tim Murtaugh hit out at the Grammy-winner on Twitter yesterday, declaring: "Nothing exposes Biden’s disdain for the forgotten working men & women of PA like campaigning with anti-fracking activist Lady Gaga.

"This desperate effort to drum up enthusiasm is actually a sharp stick in the eye for 600,000 Pennsylvanians who work in the fracking industry."

Lady Gaga soon responded, writing: "HEY TIM HEY @realDonaldTrump SO HAPPY IM GLAD TO BE LIVING RENT FREE in your HEAD". She reposted Murtaugh's statement along with animated stickers reading "LOL" and "Vote Biden", as well as the message, "Heeeey Donald... #WINNING (also, what is a fracking?) keep your jobs PA... We (heart emoji) You."

Murtaugh then thanked the singer for sharing his attack with her millions of followers - although fans overwhelmingly praised her response.

(In case you also thought 'what is a fracking'...)

Fracking allows drilling firms to access difficult-to-reach resources of oil and gas. In the US it has significantly boosted domestic oil production and driven down gas prices - but has prompted concern from environmentalists who want investment to focus on renewable energy.

Earlier in the campaign cycle Biden had suggested to voters that he favoured ending fracking, but since becoming the Democratic nominee he has said his policy is more limited - to end fracking leases on federal land.

The Trump campaign has repeatedly insisted that Joe Biden does want to end fracking in adverts targeting the Democratic candidate.

Pennsylvania is premium political turf in this election - which explains why it's getting so much love from the candidates.

The swing state moved slightly to the right when Donald Trump faced Hillary Clinton in 2016, but polls suggest Biden currently has a narrow lead.

In 2016, Trump won by 44,000 votes - the first time the state had backed a republican for president since 1988. While the city of Philadelphia is a Democratic stronghold, often delivering huge margins for the blue corner, Pennsylvania's rural areas (and former coal mining counties) tend to lean more Republican.

After Florida, Pennsylvania has the second most electoral college votes among the swing states, and should be a hive of voting activity tomorrow: About 2 in 3 likely voters have said they plan to cast their ballots in person.

This was to be the grand relaunch of the Trump re-election campaign. Coronavirus was now in the rear-view mirror. Tulsa would be the first rally since lockdown. It would be a vivid symbol of America going back to normal life, of rebirth - and Donald Trump, who’d felt like a caged animal cooped up in the White House, would be unleashed to do what he does best - firing up his audience.

As Air Force One came to a halt at Tulsa International Airport and the hatch opened, there - waiting impatiently to get out - was President Trump. He was jovial. Playful. Skittish almost. He was pouting for the cameras and was pulling teasing faces: “Shall I come down the stairs or not?” “Should I, shouldn’t I?”

And then, much later, there was his arrival back at the White House later that night. He got off the chopper and the man looked broken. His spirit crushed. In my years covering Donald Trump, I had never seen him like this. His red tie was undone. His jacket weighed heavily on his shoulders. He forced the thinnest but weariest of smiles for the cameras, and trudged back to the Residence. Disconsolate. Dishevelled. And seemingly defeated.

Over the weekend, the White House accused leading infectious disease expert Dr Anthony Fauci of playing politics over an interview he gave to the Washington Post, external, in which he said the US was in for a "whole lot of hurt".

Asked about Donald Trump and Joe Biden's approaches to the pandemic, Fauci said Biden was "taking it seriously from a public health perspective", while Trump was "looking at it from a different perspective… the economy and reopening the country".

Dr Fauci said the US needed to make an "abrupt change" in public health practices and behaviours.

The comments drew a sharp rebuke from the White House, which accused the leading epidemiologist of attempting to bolster Biden's bid for the presidency.

The US has recorded more deaths and cases than any other country, with more than 230,000 fatalities since the pandemic began.

We're getting into the final stretch, and Democratic candidate Joe Biden remains ahead in the national polls, with 52% to President Donald Trump's 43%.

But in the US, elections can be won or lost in just a handful of battleground states, where the polls indicate a much closer race - although Biden still has a lead.

Both candidates are making the most of the final day of campaigning to focus on Pennsylvania - one of the key battleground states that could determine the outcome of this year's election.

Donald Trump and Mike Pence will hold rallies in the swing state, which moved just slightly to the right in 2016's election, while Trump will keep up his intense travel schedule with other stops in North Carolina, Michigan and Wisconsin.

Democratic rival Joe Biden and his running-mate Kamala Harris will also spend Monday in Pennsylvania, before topping off their days with celebrity appearances at drive-in events: Biden will appear with Lady Gaga, while Harris will attend a separate event with musician John Legend.

As well as bringing you election news and analysis today, we'll be looking at how the coronavirus has impacted on Americans this year, and how it might affect the White House race.

According to data collated by Johns Hopkins University, deaths in the US have now passed 230,000, while more than nine million cases have been registered.

President Trump is trying to convince supporters, against the evidence of rising infections, that the disease is on the verge of being "vanquished". He has continued to stage large campaign rallies without social distancing measures.

His challenger Joe Biden has called Trump's handling of the pandemic an "insult" to its victims.

With one day left until election day, here's a rundown of today's key headlines and expected developments:

• Both candidates are making a final push on the campaign trail, with Donald Trump visiting four states on Monday: North Carolina, Pennsylvania, Wisconsin and Michigan
• Democratic candidate Joe Biden will travel to Pennsylvania, and has added a last-minute stop in Ohio
• The US in on course for the highest turnout in a century, with more than 90 million early ballots already cast
• The White House has criticised America's top infectious disease expert, Anthony Fauci, over comments he made about the pandemic. In an interview with the Washington Post, Dr Fauci said Biden was taking coronavirus "seriously from a public health perspective", while President Trump was focusing on "the economy and reopening the country"
• Fauci's comments came after a week in which the US saw record numbers of new coronavirus infections
• The FBI has launched an investigation after a convoy of Trump supporters surrounded a Biden campaign bus in Texas on Friday

Good morning from the UK, and thank you for joining our live coverage of the final day of campaigning before the US election.

As always, we'll be covering the key developments from both camps, as well as exploring our theme for today: the inescapable issue dominating 2020 - the coronavirus pandemic.
