Actor Matt Damon attended this weekend’s Save Our Schools (SOS) March in Washington, D.C. where he delivered a speech and gave media interviews afterward.

His speech, introduced by his mother (an early childhood educator herself), made many of the assembled teachers emotional enough that they cried, according to audience reports.

In the press tent after his speech, Damon had a confrontative interview, wherein a reporter said that “10 percent of teachers are bad” and should reconsider what they were doing.

“Maybe you’re a shitty cameraman,” Damon retorted.
