Steve Kerr, coach of NBA side Golden State Warriors, has launched an attack on US politicians, the National Rifle Association (NRA) and the Donald Trump’s plans to build a wall between America and Mexico hours after another fatal mass shooting.

Kerr said “nothing has been done” when asked about the tragic shooting which has left at least 17 dead at a school in Florida, including students and teachers.

The shooting is the deadliest school attack since 26 people were killed at Sandy Hook school in Connecticut in 2012 and is the sixth school shooting that has either wounded or killed students already this year.

Kerr blasted the inaction of politicians to put stricter regulations on gun control and said that “not enough people are being shot, apparently” for the government to do anything about it.

“Well, nothing has been done,” Kerr said. “It doesn't seem to matter to our government that children are being shot to death day after day in schools. It doesn't seem to matter that people are being shot at a concert, in a movie theatre. It's not enough, apparently, to move our leadership, our government, the people running this country to actually do anything. That's demoralising.”

He also urged the US people to spark the change by not voting for people who “just bow down to the NRA because they finance their campaign”, in what was a shot at Trump’s presidency.

“But we can do something about it,” he added. “We can vote people in who actually have the courage to protect peoples’ lives and not just bow down to the NRA because they finance their campaign for them.
