'I was a mess, I was sick' - US Olympian Aly Raisman describes emotional toll of confronting abuser Larry Nasser

One of the most prominent US sportswomen who testified against US sports doctor Larry Nasser, who has been handed multiple life sentences for molesting young athletes, has spoken of the emotional toll of confronting him in court.

US Olympic gymnast Aly Raisman said despite her stoic appearance in the court footage, the event took many weeks to recover from.

"I can't even put into words how difficult it is," Raisman said.

"It's not easy getting up in front of (Larry) Nasser and speaking in front of him.

"I know I looked strong in the moment, but after I was a mess. I was sick. I didn't feel good. I was exhausted. It felt like it took me weeks to recover.

"It's not easy at all and, you know, leading up to when I decided to share my story I was stressed out, I was sick, I could barely work out.

"It's not something that - it's not easy for anyone to come forward."

On Feburary 6, Nasser was sent to prison for up to 175 years in what's said to be the worst sex-abuse case in sports history.

His victims vowed to keep fighting for accountability in the scandal that upended the gymnastics world and raised alarms about the sport's ask-no-questions culture.

Long after the disgraced doctor is locked up in a federal prison, investigations into his misconduct will go on, perhaps for years.

"We have taken care of one perpetrator. We have not taken care of the systems that allowed him to flourish," said Rachael Denhollander, who filed a police report in 2016 about how Nassar had molested her 16 years earlier, when she was 15, with her mother in the room.

Watch: Florida's Governor totally refuses to answer questions on US gun laws after school massacre kills 17

Florida's Republican Governor has evaded making any comment on the state of US gun laws following the high school mass shooting that killed 17 today, instead vaguely touching on the need to improve law enforcement.

Florida Governor Rick Scott, who is a public supporter of the National Rifle Association, was asked at the close of day in Florida, whether politicians like him were "complicit" in such US mass shootings for their resistance to harsher gun laws.

The reporter asked: "Are we all in society, politicians in society included, complicit when critics say we pay lip service to the great need for mental health care in this country, and people like you who are very pro-gun, don't want to see any gun restrictions."

"When do you take a stand? Are you willing to take a stand? Are you willing to take one now that it's happened in the backyard of your won state?"

In reply, Governor Scott couldn't even manage to pay lip service to the subject, completely avoiding any reference to gun laws and simply saying there is a time to have conversations about improving mental health services and law enforcement.

"My heart goes out to everyone impacted today. Um, all of us can internalise this if it were to happen to their family," Mr Scott said.

"You know, all of us want to live in a safe community, and there's a time to continue to have these conversations about how through law enforcement, how through mental illness funding that we make sure people are safe, and we'll continue to do that."

At least seventeen people have been confirmed dead by authorities in the fatal Florida high school shooting today. 

Authorities said 19-year-old Nikolas Cruz is in custody after the attack Wednesday that claimed 17 lives at Marjory Stoneman Douglas High School in Parkland.

Officials say Cruz was a former student, having been expelled from the school.

Classmates of Cruz have described him as having a fixation on guns, and owning numerous firearms.

Broward county mayor Beam Furr told CNN that Cruz had previously attended a mental health clinic, but had not been seen there for more than a year.

"It wasn’t like there wasn’t concern for him. We try to keep our eyes out on those kids who aren’t connected," Mayor Furr said.

"Most teachers try to steer them toward some kind of connections. In this case, we didn’t find a way to connect with this kid."

Also fronting the press conference, held around 3.30 (NZDT), was Broward County Sheriff, Scott Israel, who added the fresh information that one of the victims was a coach at the school, and a deputy sheriff’s son was shot, but doesn’t have life-threatening injuries.

In an earlier press conference, Broward County Florida Sheriff Scott Israel said 12 were killed within the building, two outside, one on the street and two lost their lives at the hospital. 

"I'm sadden to say 17 people lost their lives."

"There are people that are still undergoing surgery."

"Just pray for this city, pray for this school, the parents, the folks that lost their lives."

"It's a horrific, horrific day. It's just horrible."

Sheriff Israel said the gunman, believed to be 19-year-old Nicholas Cruz had "countless magazines" and is believed to have used one AR 15 rifle.

He also said Cruz was expelled for disciplinary reasons from the high school.

Embattled Barnaby Joyce takes leave from Australia's Parliament, won't fill in as Acting PM for Turnbull

Australia's Deputy Prime Minister Barnaby Joyce will be taking leave next week and won't stand in as the nation's leader while Malcolm Turnbull is away.

The prime minister, who is heading to Washington next week, told parliament todaythat leave had been approved for the embattled Nationals leader from February 19 to 25.

Mr Joyce has been under fire over his acceptance of a rent-free apartment offered to him by businessman Greg Maguire and whether any rules have been broken in regard to jobs provided to his former staffer and now partner Vikki Campion.

Finance Minister Mathias Cormann will be acting prime minister during the period, as he is government leader in the Senate.

Labor leader Bill Shorten asked the prime minister whether the provision of leave confirmed the deputy prime minister could not do his job.

"Or are we simply meant to believe it's all a big coincidence?" Mr Shorten said.

Labor opened a new front in the scandal on today, asking Mr Joyce about taxpayers forking out $A5000 on meals and drinks for a March 2016 function - which he attended - at the Quality Hotel Powerhouse in Armidale, owned by Greg Maguire.

Mr Maguire last year provided a rent-free townhouse to Mr Joyce and his partner Vikki Campion in Armidale.

"I have to admit I was unaware of that $5000 payment," Mr Joyce told parliament, pledging to take the question on notice.

"It would not seem surprising in a multiple-billion-dollar department that I'm not aware of a $5000 payment."

The deputy prime minister earlier in the day survived a vote aimed at forcing him out of parliament.

The vote failed 73-70, with the government using its numbers.

Labor seized on media reports that Mr Joyce had personally solicited the use of the townhouse from Mr Maguire - a potential breach of the ministerial code of conduct.

But Mr Joyce told parliament Mr Maguire had contacted him, and in any case it occurred at a time he was seeking preselection for the New England by-election and was not a minister.

"It was at that time that Mr Maguire approached me, as did many other friends to offer support," Mr Joyce told parliament today.

"He said, 'You're living out of a suitcase, and this is basically something that I should try and help you with'.

"I took him up on the offer but I offered to pay for it."

Mr Maguire knocked back his offer to pay rent and provided the townhouse free for six months.

Opposition Leader Bill Shorten said Mr Joyce's position as deputy prime minister was no longer tenable due to his conflicts of interest.

"The prime minister has a ministerial code of conduct which, if he doesn't uphold, is not worth the paper it's written on," Mr Shorten said.

Meanwhile, new figures show Deputy Prime Minister Barnaby Joyce clocked up more than $A227,000 in government aircraft flights in the first half of 2017.

Figures released Thursday showed between January 1 and June 30 last year Mr Joyce's work flights on government planes, which also included periods when he was acting prime minister, totalled $227,508.

The report noted Mr Joyce flew with Ms Campion on three occasions, in February and April, at a cost to taxpayers of $A9787.
