In the wake of deadly violence following a white supremacist rally, George and Amal Clooney have donated $1 million (€850,000) to a civil rights advocacy organisation that monitors hate groups, the Southern Poverty Law Center.
The couple, who made the donation via their Clooney Foundation for Justice, join a number of others giving funds in recent weeks to anti-discrimination organisations.
There has been a surge in donations since clashes between white supremacists and anti-racism protesters at a demonstration in Charlottesville, Virginia, left one dead.
"What happened in Charlottesville, and what is happening in communities across our country, demands our collective engagement to stand up to hate," the Clooneys said in a statement announcing the grant.
"We are proud to support the Southern Poverty Law Center in its efforts to prevent violent extremism in the United States."
The unrest in Charlottesville at the rally called by neo-Nazi and other far-right extremists saw one woman, Heather Heyer, killed after an avowed white supremacist ploughed a car into a group of counter-protesters.
President Donald Trump faced fierce criticism following his comments that "both sides" were to blame for the violence that highlighted racial tensions in a nation on edge.
Since the violence in Charlottesville, the Anti-Defamation League - one of the oldest anti-discrimination organisations fighting anti-semitism in the US - has seen its donations spike sharply.
21st Century Fox chief executive James Murdoch recently announced he was giving $1 million to that group.
Donations such as that one, as well as those from corporations like Apple, Uber and MGM Resorts, yielded a rise of "1,000%" last week, according to ADL spokeswoman Betsaida Alcantara, compared to the weekly average donations since the beginning of the year.
JP Morgan also joined the ranks of the donors, announcing a million-dollar gift to be shared by the ADL and the SPLC, according to US media.
Another organisation combatting racism and anti-semitism, the Los Angeles-based Simon Wiesenthal Center, has also recorded major donations since then.
One came from actor and former California governor Arnold Schwarzenegger.
