Donald Trump doubled down on his endorsement of Alabama Republican U.S. Senate candidate Roy Moore on Friday, during a Florida rally just 15 miles from the Yellowhammer State's border.

He jetted to Florida's Panhandle region to rally supporters in Pensacola, a town that's just a short drive from this month's political ground zero.

He took the Christmas-decorated stage to the enthusiastic screams in an arena full of people who weren't deterred by near-freezing temperatures.

Pensacola shares a media market with Mobile, Alabama, one of a handful of metro areas whose voters will decide Tuesday's strange U.S. Senate special election between Republican Roy Moore and Democrat Doug Jones.

Amid a litany of policy promises and complaints about Democrats in Congress, he stopped and pointed to a man in the crowd.

'This guy's screaming, "We want Roy Moore!' He's right,' Trump said.

President Donald Trump took to the stage to the screams of enthusiastic Trump-lovers in an arena where near-freezing temperatures left the seating areas less than full

'Democrats in Congress want open borders, higher taxes and government-run health care that doesn't work,' he said.

'They don't want to vote for our tax cuts because they want tax increases. That's why we need a Republican in the House. We need a Republican in the Senate. We need more of them.'

Trump asked how many Alabamians were in his audience, and a wild whoop rose to the rafters of the hockey arena where he was holding court.

The president also jabbed at one of the nine women who have accused Moore of sexual misconduct, Beverly Young Nelson, who revised a detail of her story on Friday.

Nelson conceded on 'Good Morning America' that small amount of a high-school yearbook inscription her lawyer Gloria Allred had attributed to Moore was actually written in her own hand.

Her addition was a date and the name of a restaurant where she says Moore scrawled a Christmas message signed with 'love.'

Nelson claims Moore, then in his 30s, groped her and tried to force her to perform a sex act in his car when she was 16 years old.

Friday's tweak to her story was music to Trump's ears hours later.

'You know the yearbook? Did you see that? That was a little mistake made. She started writing things in the yearbook,' the president scolded.

'Gloria Allred! Anytime you see her you know something's going wrong,' he added, referring to Nelson's attorney.

'Democrats in Congress want open borders, higher taxes and government-run health care that doesn't work,' he said. 'They don't want to vote for our tax cuts because they want tax increases. That's why we need a Republican in the House. We need a Republican in the Senate. We need more of them'

The stage was Christmas-decorated. Trump announced to the crowds that he had given them an early Christmas present of tax cuts

'We cannot afford to lose a seat in the very, very close United States Senate. We can't afford it. We can't afford to have a liberal Democrat whjo is completely controlled by Nancy Pelosi and Chuck Schumer,' Trump said

Citing crime fighting, immigration, military funding, veterans programs and his promised border wall, Trump issued a full-throated request for pro-Moore voters to go to the polls next week.

'We cannot afford to lose a seat in the very, very close United States Senate. We can't afford it. We can't afford to have a liberal Democrat whjo is completely controlled by Nancy Pelosi and Chuck Schumer,' he said.

'We want jobs, jobs, jobs. So get out and vote for Roy Moore!'

Moore stands accused of sexual misconduct by nine different women, including two who say he groped them while they were 14 and 16 years old. He has denied everything.

But Trump has endorsed him anyway, underscoring Moore's denials and insisting that another Senate Democrat would make passing his agenda far more difficult.

'LAST thing the Make America Great Again Agenda needs is a Liberal Democrat in Senate where we have so little margin for victory already,' Trump tweeted Friday morning. 'VOTE ROY MOORE!'

'The Pelosi/Schumer Puppet Jones would vote against us 100% of the time. He's bad on Crime, Life, Border, Vets, Guns & Military,' he wrote.

Beverly Young Nelson claims U.S. Senate candidate Roy Moore groped her in a car when she was 16 years old and he was a rising legal star, but now she concedes that she herself wrote a few lines of an entry in her high school yearbook that was previously attributed to him

Nelson now says that while Moore wrote this message in her high school yearbook, she added the date at the bottom and the name of the restaurant where she claims he wrote it

Nelson claims she was a 16-year-old waitress when Moore groped her and tried to force her to perform a sex act in his car.

Moore denies ever having known her but did rule against her in a divorce proceeding years later when he was a judge.

On Friday, Nelson told 'Good Morning America' that she still fears Moore's potential impact in the U.S. Senate, but softened her earlier insistence that an inscription in her high school yearbook was entirely written in Moore's hand.

She admitted adding the date and location under Moore's signature, despite her attorney Gloria Allred's earlier claim that the Republican candidate wrote it all.

She added the date '12-22-77' and a restaurant name – 'Olde Hickory House' – to the yearbook inscription, she said.

Allred has presented the yearbook page as proof that Moore, then in his 30s, sought an inappropriate relationship with Nelson at the time.

After the rally Trump tweeted: 'This is your land, this is your home, and it's your voice that matters the most. So speak up, be heard, and fight, fight, fight for the change you've been waiting for your entire life! MERRY CHRISTMAS and THANK YOU Pensacola, Florida!'

Trump also took credit for an economic book that has driven the stock market to dozens of record-setting days, and claimed Democratic administrations had nose-dived 401(k) values

Moore insisted last week during a campaign rally that he is completely innocent.

'These allegations are completely false. They're malicious. Specifically, I do not know any of these women, nor have I ever engaged in sexual misconduct with any woman,' Moore said.

Nelson, who says she voted for Trump, tells a different story.

'He was trying to pull me toward – in between his legs. It was terrible. I was bound and determined that I was not going to be raped by him,' she recalled on Friday. 'I was terrified.'

'It sickens me to wonder what may go on with him if he gets into office,' she added.

'Maybe, you know, he could be doing this still. We don't know. And then again I hope that he's changed. I pray that he's changed. I really do.'

Trump said he thought no president had had a more successful honeymoon period, but cited little to support that conclusion. 'I think the answer is "no," but I have to be very accurate because of the fake news back there,' Trump jabbed, pointing to a cadre of journalists staring him down

White House Chief Deputy Press Secretary Raj Shah downplayed the geographical significance of Pensacola on Friday as he spoke with reporters aboard Air Force One. 'It's not that he's not going to Alabama. It's that he is going to Pensacola,' Shah said. 'Pensacola is Trump country. This is a part of the state that voted overwhelmingly for the president in 2016. He'll be traveling back to Florida from time to time.' Trump speaks at the rally above

White House Chief Deputy Press Secretary Raj Shah downplayed the geographical significance of Pensacola on Friday as he spoke with reporters aboard Air Force One.

'It's not that he's not going to Alabama. It's that he is going to Pensacola,' Shah said. 'Pensacola is Trump country. This is a part of the state that voted overwhelmingly for the president in 2016. He'll be traveling back to Florida from time to time.'

The White House has said the president wouldn't campaign for the former state Supreme Court judge in advance of Tuesday's election, but that pledge has served as a fig leaf covering his advocacy on Twitter – and, now, in a city across the border.

Shah said of the raft of claims facing Moore that 'we find these allegations to be troubling and concerning and they should be taken seriously.'

'But Roy Moore has also maintained that these allegations aren't true and that should also be taken into account,' he added.

Trump began his speech Friday by taking pot shots at political reporters, telling saying he would 'cut straight through the fake news media. We're going to speak the plain truth. And really the truth you want to hear.'

On a day when CNN had to correct a story that had claimed Trump's son Donald Jr. was tipped off to a cache of hacked emails before WikiLeaks published them – the truth was that it came afterward – the president showed no mercy.

'CNN apologized just a little while ago. They apologized!' he exclaimed as a few in the audience yelled, 'CNN sucks!'

'Oh thank you CNN, thank you so much,' Trump gushed. 'You should have been apologizing for the last two years!'

He said the reporters he loves to hate 'have been apologizing left and right,' citing a flawed ABC News report that falsely claimed he had instructed his son-in-law Jared Kushner to contact Russians while he was still a presidential candidate.

'They took this fraudster from ABC. They suspended him. They should have fired him,' he said of correspondent Brian Ross. 'He drove the stock market down 350 points in minutes.'

'Get yourself a lawyer and sue ABC News,' he blared.

Trump kicked off his speech by promising a Christmas present in the form of tax reform, as House and Senate leaders prepared to hammer out the differences between their respective bills.

'I can't wait to sign that tax cut ... We're going to cap off an incredible first year in office,' he pledged.

Trump said he thought no president had had a more successful honeymoon period, but cited little to support that conclusion.

'I think the answer is "no," but I have to be very accurate because of the fake news back there,' Trump jabbed, pointing to a cadre of journalists staring him down.

In a moment ripped from the greatest-hits reel of his rise to power, Trump returned to calling America's election system 'rigged,' saying there's 'a lot of sickness' in political institutions.

He blasted progressives who now embrace the word 'resist' as a rallying cry, jabbing Hillary Clinton in the process.

'Hillary resisted, and you know what happened?' he asked. 'She lost the election in a landslide!'

'They're resisting the will of the American people. That's what they're resisting,' he said.

The president whacked Clinton for failing to campaign in Wisconsin, a state her political advisers thought was a sure thing.

'I guess the Russians told her not to go,' he grinned.

Trump also took credit for an economic boom that has driven the stock market to dozens of record-setting days, and claimed Democratic administrations had nose-dived 401(k) values.

'With us it goes up, with them it goes down. And that's the end of it,' he said.

After the rally Trump tweeted: 'This is your land, this is your home, and it's your voice that matters the most. So speak up, be heard, and fight, fight, fight for the change you've been waiting for your entire life! MERRY CHRISTMAS and THANK YOU Pensacola, Florida!'

Trump won Florida by just 1.2 per cent of the vote, a crucial part of his stunning victory over Democrat Hillary Clinton.

He held three campaign rallies in Pensacola last year, including an outdoor amphitheater less than a week before Election Day that ended in fireworks.

Another, in January 2016, came while the rest of the Republian field was preoccupied with early primary states.

That's where the USA Freedom Kids, a trio of sequin-spangled girls who later sued the Trump campaign in a breach of contract dispute, danced and lip-synched to a patriotic tune.

The president will fly to his Mar-a-Lago resort in Palm Beach, Florida after Friday night's rally and spend part of Saturday at the opening of the new Mississippi Civil Rights Museum.

Trump isn't expected to speak at the event. Prominent black civil rights leaders including Reps. John Lewis and Bennie Thompson, along with former Mississippi Gov. Ray Mabus, have said they won't attend because he will be the main draw.
