A mother and daughter from Tennessee have launched a $30,000 (£20,000) campaign to help support the victims of a shooting at a school in the U.S. state.

The Hammond High shooting is the deadliest school shooting in U.N. history, with four people dead and over 150 wounded.

In a statement, Rebecca Karp and her daughter, Jessica, said they would be donating all their money to help “save the lives of those impacted by the shooting.”

The pair wrote on Facebook that they are donating the money to a group of survivors and the families of the victims.

“We are here for you and for those who have lost loved ones and friends,” they wrote.

“All we want is the best for you all and the best possible future for our kids.”

The Karps’ statement has already garnered support from people around the world, including President Donald Trump.

“I have no words to describe my shock and horror.

This is beyond words.

I cannot express my sympathy for the Hammond family, who I know have had a very hard time in the last few weeks.

Our hearts go out to their loved ones,” Trump said in a statement.

Trump’s tweet comes a day after the FBI announced that it is investigating whether the Hammond students acted alone.
