California Rep. Maxine Waters called on artists to be socially active in a surprise appearance at the MTV Movie and TV Awards on Sunday.

“Artists, actors, singers and citizens have a unique opportunity — the ability to speak out and inspire change,” she said.

Waters, who has seen her profile grow among young people as “Auntie Maxine for her frequent and fiery criticism of President Donald Trump, presented the Best Fight Against the System award with actress Tracee Ellis Ross.

Without making an overt statement about Trump, Waters did point out in announcing the award, “Each of these stories pushes back against the bullies and uses their platform to inspire us all.”

Ross praised Waters leadership, saying, “Thank you for being an example for all of us, especially in these times.”

The winner of the award was “Hidden Figures,” which focuses on the story of African-American’s role in the early space program.
