Celebrities and Politicians React to the Monterey Park Mass Shooting

"On a traditional day of celebration, today it is also marked by tragedy," Kim tweeted. "We often speak of the term 'community.' As important as it is for ours to come together of times of celebration, perhaps it's even more important to be there for each another in times of loss."

Kim also spoke about the shooting at the Sundance Film Festival. "I'm sure many of you are aware that last night in Monterey Park, 10 people were killed and shot and another 10 were wounded by a gunman at Lunar New Year festivities," he said.

The "Lost" star continued, "We are here for our community today."
