Several students who survived the school shooting in Florida last week, in which 17 people were slain, have announced they are holding a march in Washington, D.C. on March 24 to demand stricter gun laws.

Actor George Clooney and his wife Amal Clooney have reacted to the news of the march by announcing they are donating half a million dollars to help pay for it.

People reported on Tuesday:

The couple announced they are making a donation to the upcoming “March for Our Lives” event in the name of their 8-month-old twins Ella and Alexander — and their family will attend. George also praised the survivors of the Florida school shooting for their bravery in a statement to PEOPLE.

“Amal and I are so inspired by the courage and eloquence of these young men and women from Stoneman Douglas High School,” he said. “Our family will be there on March 24 to stand side by side with this incredible generation of young people from all over the country, and in the name of our children Ella and Alexander, we’re donating $500,000 to help pay for this groundbreaking event.”

He added, “Our children’s lives depend on it.”
