Hillary Clinton was a surprise presenter at the Child Mind Institute gala to honor co-founder Brooke Garber Neidich.

Also at the event were Mary-Kate Olsen, Jesse Eisenberg, Brooke Shields, Dr. Harold S. Koplewicz and Ruth Westheimer. Ali Wentworth was scheduled to co-host with anchor hubby George Stephanopoulos, but he had to miss it to cover the impeachment hearings.

Said Clinton, “The true test of any society is how we treat the most vulnerable among us, particularly children. Brooke shares that belief … Even more importantly, she acts on it every day.” The event raised $7 million.
