Apple CEO Tim Cook is now among the growing list of Silicon Valley CEOs who have openly condemned the violence in Charlottesville, Virginia. In a note to employees on Wednesday, Cook denounced President Donald Trump's lukewarm response to the controversial demonstration.

"I disagree with the president and others who believe that there is a moral equivalence between white supremacists and Nazis, and those who oppose them by standing up for human rights," Cook writes. "Equating the two runs counter to our ideals as Americans"

Cook says that "hate is a cancer and left unchecked it destroys everything in its path."

As a way to step up to "help organizations who work to rid our country of hate," Apple will be making a $2 million contribution against hate: $1 million to the Southern Poverty Law Center and another million to the Anti-Defamation League.

Additionally, Apple will match two-for-one its employees' donations to the above organizations as well as other human groups from now through September 30.

This isn't the first time Cook has taken a stance against discrimination and stood up for human rights. Since 2013, he has been auctioning off lunch dates to support the Robert F. Kennedy Human Rights group. To date, the auctions have raised $1.82 million.

While this list isn't exhaustive, here are six other causes Cook has donated to in the past.
