Greta Thunberg led a protest at the White House on Friday. But she wasn’t looking to go inside, saying, “I don’t want to meet with people who don’t accept the science.”

The young Swedish activist joined a large crowd of protesters who had gather outside, calling for immediate action to help the environment and reverse an alarming warming trend in average global temperatures.

She says her message for President Trump is the same thing she tells other politicians: Listen to science, and take responsibility.

Thunberg, 16, will spend nearly a week in Washington, D.C. But she says she doesn’t plan to meet with anyone from the Trump administration during that time.
